Describe an equilibrium in everyday life that illustrates a state of balance between two opposing processes. What things are equal in an equilibrium? First, notice that when we choose a pivot point, there is no expectation that the system will actually pivot around the chosen point. Hence, it is not affected by any volume changes since its volume would remain constant throughout the reaction. Your final answers should have correct numerical values and correct physical units. The forward reaction is exothermic. Distance from nearest urban area. This reversible reaction has reached dynamic equilibrium. Earn points, unlock badges and level up while studying. We're going to focus on three in particular: But before we dive into these processes, you need to understand compromise conditions. Using the equilibrium concentrations given to us, the equation for Kc looks like this: Calculating Kc. Please subscribe to view the answer, How does equilibrium represent the balancing of opposing processes? Increasing the pressure of an equilibrium favours the reaction that produces ____ number of moles of gas. Equilibrium constants are values that compare the amount of the products of a reaction at equilibrium to the amount of reactants. However, decreasing the temperature too much decreases the overall rate of reaction, and so a compromise temperature that is somewhere in the middle is used instead. It is also known as dynamic equilibrium. Say you want to cook an egg. It works the other way too - even if we start with just C and D, and no A or B, we'll end up with the same equilibrium constant. Equilibrium is achieved if all the forces acting on an object are balanced. By the end of this section, you will be able to: All examples in this chapter are planar problems. A few examples of equilibrium are: A book kept on a table at rest. What is meant by a stress on a reaction at equlibrium? Here's the equation and the conditions: C2H4(g) + H2O(g) C2H5OH(g) H = -46 kJ mol-1. Problem 34 Given the fact that the concentrations of reactants and products are not changing, why is the word dynamic used to describe chemical equilibrium?

By the second law of motion, we know that the acceleration in such bodies is zero. We defined chemical equilibrium at the start of the article. They can then feed these variables into a clustering algorithm to perhaps identify the following clusters: Cluster 1: Small family, high spenders. Thus the diver achieves the constant velocity and hence sets the dynamic equilibrium examples. The ratio of the concentrationd of the procductd over that of reactant at equilibrium. CH + H CH + heat Human homeostasis is a term given to the way the human body interacts with itself to maintain a balance. Equilibrium in the brain: Excitation and inhibition remain balanced, even when the brain undergoes reorganization. ScienceDaily. Let's look at some real-life examples. at equilibrium, the rate of evaporation is equal to the rate of condensation. Accordingly, we use equilibrium conditions in the component form of Equation 12.7 to Equation 12.9. For the reaction Aa(g) + Bb(g) Cc(g) + Dd(g), Kp = pCc x pDdpAa x pBb. Each drop of rain moves with the same velocity. This is because all gases take up equal volume at the same temperature and pressure, and having fewer molecules of gas in a container reduces the pressure. a. heat + CaCo3(s) CaO(s) + CO2(g) Ksp- solubility product constant for a saturated solution at equilibrium. What does this all mean? Name the reactants used to make methanol. Kw looks at the dissociation of water molecules into H+ and OH- ions. Also note that a free-body diagram for an extended rigid body that may undergo rotational motion is different from a free-body diagram for a body that experiences only translational motion (as you saw in the chapters on Newtons laws of motion). Take the equation 2H(g) + 2I(g) 3J(g) + K(g). It states that if the conditions of a dynamic equilibrium in a closed system change, the position of the equilibrium will shift to counteract the change. of cube= (5.25)= 144.70cm The forward reaction is exothermic. It is made up of three semicircular canals and two otolith organs, known as the utricle and the saccule. The reaction that produces the fewest moles of gas. They are affected by temperature but unaffected by variables such as concentration and pressure. Define equilibrium. Both reactions are at equilibrium. So if we have two moles of A in the equation, and the equilibrium concentration of A is 0.5 mol dm-3, [A]eqma = 0.52. The rates of the forward and backward reactions are the same, and the concentrations of products and reactants remain constant. WebQuestion: Throughout this unit you were looking at two or three examples of how equilibrium applies to everyday life. The forward reaction is exothermic. If the earths rotational velocity is not constant, then the concept of 24 hours for a day and 365 days for a year would be a contradiction.Image credits: Pixabay, The raindrop reaches the earth from the cloud at a certain velocity. This is a natural choice for the pivot because this point does not move as the stick rotates. Quiz 1. If you try to fill the water in a bucket having a hole, the bucket will be in dynamic equilibrium. (a) Use the free-body diagram to write a correct equilibrium condition.

This means a lower temperature favours the forward reaction and increases the yield of ammonia. WebExamples of equilibrium reactions in industry include methanol, ethanol, and ammonia production. and you must attribute OpenStax. If [N2]= .05200 mol/L and [O2]= .00120 mol/L, what is the concentration of NO at equilibrium? Due to air resistance and friction, the increase in speed of the raindrop is balanced to achieve constant velocity. Jan 19, 2023 OpenStax. Calculate the molar solubility of the compound at this temperature. In our daily life, we encounter many systems moving with constant velocity. WebThe second edition of this book introduces the interpretation of ternary equilibrium diagrams for many alloy systems. WebStatic equilibrium in a reaction refers to the phase where the reaction is at a halt or there is no reaction taking place between the reactants or the products. Here's the equation for the production of methanol: CO(g) + 2H2(g) CH3OH(g) H = -91 kJ mol-1. WebA state of rest or balance due to the equal action of opposing forces. When the weights at both platforms become equal, the scale achieves the dynamic equilibrium.Image credits: Pixabay. The molecules only partially dissociate, meaning that the system forms a dynamic equilibrium. How can an equilibrium system contain small & unchanging amounts of products yet have large amounts of reactants? At this point, your work involves algebra only. Sara Ross. In this way the second equilibrium condition is, Selecting the +y+y-direction to be parallel to FS,FS, the first equilibrium condition for the stick is, Substituting the forces, the first equilibrium condition becomes, We solve these equations simultaneously for the unknown values m3m3 and FS.FS. a. the system will try to minimize the effect of the added CO by consuming more reactants forming more products. Explain the difference between a homogeneous equilibrium & a heterogeneous equilibria? Catalysts would speed up both forward and backward reaction Now we generalize this strategy in a list of steps to follow when solving static equilibrium problems for extended rigid bodies. (a) Geometry and (b) free-body diagram for the door. What is the SI unit of acceleration Class 9? Solution: A We must first find the initial concentrations of the substances present.

The semicircular canals and the otolith organs are filled with fluid. a is the molar ratio of A. of the users don't pass the Chemical Equilibrium quiz! Before opening the bottle, the gaseous carbon dioxide and the aqueous carbon dioxide are balanced by the dynamic equilibrium. If they do not, then use the previous steps to track back a mistake to its origin and correct it. The key word here is uniform. We know from our previous studies that the CM of a uniform stick is located at its midpoint, so this is where we attach the weight w, at the 50-cm mark. Show answer Answer As soon as the bottle seal opened, the gaseous carbon dioxide dissolved in liquid carbon dioxide and spilt out of the bottle with bubbles. Note that setting up a free-body diagram for a rigid-body equilibrium problem is the most important component in the solution process. But some reactions are reversible. At this point, we do not need to convert inches into SI units, because as long as these units are consistent in Equation 12.23, they cancel out. Equal balance between any powers, influences, etc. This is called shifting the position of the equilibrium. Because it is simply a ratio of concentrations. As long as the angle in Equation 12.10 is correctly identifiedwith the help of a free-body diagramas the angle measured counterclockwise from the direction of the lever arm to the direction of the force vector, Equation 12.10 gives both the magnitude and the sense of the torque. WebDynamic Equilibrium can be defined as the state of a given system in which the reversible reaction taking place in it stops changing the ratio of reactants and products, but there is a movement of substances between the reactants and the products. b. decreasing temp= right And there could be a variety of examples here. As an example of this in real life, think about a saucepan of water that you are heating to boil some potatoes. Find Kc. We show reversible reactions using half arrows: . There are many examples of systems at equilibrium. the equilibrium will shift on the left and Keq is lowered, Changing the volume of the system alters the equlibrium position of this equilibrium, N2(g) + 3H2(g) 2NH3(g), but a similar change has no effect on this equilibrium H2(g) + Cl2(g) 2HCl(g). Calculate the equilibrium constant of hydrogen when [CO2]= .320 mol/L, [H2O]= .240 mol/L, and [CO]= .280 mol/L, [H2]= [H2O][CO]/Keq[CO2] If you are redistributing all or part of this book in a print format, Be perfectly prepared on time with an individual plan. You put the reactants together, supply them with enough energy and provide just the right conditions, and they react to form new products. Partial pressure is the pressure a gas would exert if it occupied a container by itself. 
3. [NO]2]= Keq[O2][N2] Hence, reactants are highly favored compared to products. Why is the concentration of a solid not included as part of the solubility product constant? Identify the questions you need to answer. You'll also be able to have a go at some more examples. Homeostasis keeps our body temperature nearly constant.

We introduced a problem-solving strategy in Example 12.1 to illustrate the physical meaning of the equilibrium conditions. d. removing CH3OH from the system La velocidad de las reacciones hacia delante y hacia atrs son iguales. The magnitude of friction is obtained by solving Equation 12.28: f=F=150.7N.f=F=150.7N. WebA: Equilibrium is the condition in which a chemical reaction and the reaction occurring in the reverse Q: What is the relationship between the forward and reverserates for a reaction at equilibrium? Keq[O2][N2]= 1.96 x 10- mol/L. PCl(g) PCl(g) + Cl(g), Keq= (.0037 mol/L)(.0174 mol/L)/(.00315 mol/L)= .002. Describe an equilibrium in everyday life that illustrates a state of balance between two opposing processes. What things are equal in an equilibrium? First, notice that when we choose a pivot point, there is no expectation that the system will actually pivot around the chosen point. Hence, it is not affected by any volume changes since its volume would remain constant throughout the reaction. Your final answers should have correct numerical values and correct physical units. The forward reaction is exothermic. Distance from nearest urban area. This reversible reaction has reached dynamic equilibrium. Earn points, unlock badges and level up while studying. We're going to focus on three in particular: But before we dive into these processes, you need to understand compromise conditions. Using the equilibrium concentrations given to us, the equation for Kc looks like this: Calculating Kc. Please subscribe to view the answer, How does equilibrium represent the balancing of opposing processes? Increasing the pressure of an equilibrium favours the reaction that produces ____ number of moles of gas. Equilibrium constants are values that compare the amount of the products of a reaction at equilibrium to the amount of reactants. However, decreasing the temperature too much decreases the overall rate of reaction, and so a compromise temperature that is somewhere in the middle is used instead. It is also known as dynamic equilibrium. Say you want to cook an egg. It works the other way too - even if we start with just C and D, and no A or B, we'll end up with the same equilibrium constant. Equilibrium is achieved if all the forces acting on an object are balanced. By the end of this section, you will be able to: All examples in this chapter are planar problems. A few examples of equilibrium are: A book kept on a table at rest. What is meant by a stress on a reaction at equlibrium? Here's the equation and the conditions: C2H4(g) + H2O(g) C2H5OH(g) H = -46 kJ mol-1. Problem 34 Given the fact that the concentrations of reactants and products are not changing, why is the word dynamic used to describe chemical equilibrium? The water sink is one among such dynamic equilibrium examples. True or false? The boiling water in a closed system. C(FeCl2)= .15/3= .05M (1) The condition in which all acting influences are balanced or canceled by equal opposing forces, resulting in a stable system. s= 5 root 4.0 x 10/108= 3.3 x 10M. You will be evaluated on your ability to: Describe the equilibrium systems, showing your understanding of the components of each system (reactants and products), where they occur in nature or industry and how they interact. By the second law of motion, we know that the acceleration in such bodies is zero. We defined chemical equilibrium at the start of the article. They can then feed these variables into a clustering algorithm to perhaps identify the following clusters: Cluster 1: Small family, high spenders. Thus the diver achieves the constant velocity and hence sets the dynamic equilibrium examples. The ratio of the concentrationd of the procductd over that of reactant at equilibrium. CH + H CH + heat Human homeostasis is a term given to the way the human body interacts with itself to maintain a balance. Equilibrium in the brain: Excitation and inhibition remain balanced, even when the brain undergoes reorganization. ScienceDaily. Let's look at some real-life examples. at equilibrium, the rate of evaporation is equal to the rate of condensation. Accordingly, we use equilibrium conditions in the component form of Equation 12.7 to Equation 12.9. For the reaction Aa(g) + Bb(g) Cc(g) + Dd(g), Kp = pCc x pDdpAa x pBb. Each drop of rain moves with the same velocity. This is because all gases take up equal volume at the same temperature and pressure, and having fewer molecules of gas in a container reduces the pressure. a. heat + CaCo3(s) CaO(s) + CO2(g) Ksp- solubility product constant for a saturated solution at equilibrium. What does this all mean? Name the reactants used to make methanol. Kw looks at the dissociation of water molecules into H+ and OH- ions. Also note that a free-body diagram for an extended rigid body that may undergo rotational motion is different from a free-body diagram for a body that experiences only translational motion (as you saw in the chapters on Newtons laws of motion). Take the equation 2H(g) + 2I(g) 3J(g) + K(g). It states that if the conditions of a dynamic equilibrium in a closed system change, the position of the equilibrium will shift to counteract the change. of cube= (5.25)= 144.70cm The forward reaction is exothermic. It is made up of three semicircular canals and two otolith organs, known as the utricle and the saccule. The reaction that produces the fewest moles of gas. They are affected by temperature but unaffected by variables such as concentration and pressure. Define equilibrium. Both reactions are at equilibrium. So if we have two moles of A in the equation, and the equilibrium concentration of A is 0.5 mol dm-3, [A]eqma = 0.52. The rates of the forward and backward reactions are the same, and the concentrations of products and reactants remain constant. WebQuestion: Throughout this unit you were looking at two or three examples of how equilibrium applies to everyday life. The forward reaction is exothermic. If the earths rotational velocity is not constant, then the concept of 24 hours for a day and 365 days for a year would be a contradiction.Image credits: Pixabay, The raindrop reaches the earth from the cloud at a certain velocity. This is a natural choice for the pivot because this point does not move as the stick rotates. Quiz 1. If you try to fill the water in a bucket having a hole, the bucket will be in dynamic equilibrium. (a) Use the free-body diagram to write a correct equilibrium condition. Because the weight is evenly distributed between the hinges, we have the fourth equation, A y = B y. Should any of the examples be a buffer system, identify it as such. e. decreasing the volume of the system. Solved by verified expert. b. The process of equilibrium governs many of the chemical reactions taking place in the human body. When an equilibrium shifts to the right, what happens to the following? You can find this by dividing the number of moles of the gas at equilibrium by the total number of all the moles of gas in the system. NetLogo In the human body, equilibrium plays a prominent role in. In a reversible reaction, the forward reaction is exothermic. We will then look at examples of how reversible reactions are used in industry. Ammonia is produced industrially using something called the Haber process. Examples of equilibrium in everyday life. the vestibule (has the saccule and utricle) that connects the semicircular canals to the cochlea. b. decrease concentration of ethylene In every day life, acids and bases play a role in everything from digestion of the foods you eat to the function of the medicine you take and even the cleaning products you use. However, a low temperature slows the rate of reaction and so a compromise temperature of 670 K is used. Notice that in our frame of reference, contributions to the second equilibrium condition (for torques) come only from the y-components of the forces because the x-components of the forces are all parallel to their lever arms, so that for any of them we have sin=0sin=0 in Equation 12.10. Explain the difference between Qsp & Ksp. When you return, the previously-runny egg has turned solid and is ready to eat. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, WebTo every action, there is always an equal but opposite reaction. According to this law, the action is always accompanied by a reaction force and the two forces must always be equal and opposite. Sara R. Numerade Educator. This means a lower temperature favours the forward reaction and increases the yield of ammonia. WebExamples of equilibrium reactions in industry include methanol, ethanol, and ammonia production. and you must attribute OpenStax. If [N2]= .05200 mol/L and [O2]= .00120 mol/L, what is the concentration of NO at equilibrium? Due to air resistance and friction, the increase in speed of the raindrop is balanced to achieve constant velocity. Jan 19, 2023 OpenStax. Calculate the molar solubility of the compound at this temperature. In our daily life, we encounter many systems moving with constant velocity. WebThe second edition of this book introduces the interpretation of ternary equilibrium diagrams for many alloy systems. WebStatic equilibrium in a reaction refers to the phase where the reaction is at a halt or there is no reaction taking place between the reactants or the products. Here's the equation for the production of methanol: CO(g) + 2H2(g) CH3OH(g) H = -91 kJ mol-1. WebA state of rest or balance due to the equal action of opposing forces. When the weights at both platforms become equal, the scale achieves the dynamic equilibrium.Image credits: Pixabay. The molecules only partially dissociate, meaning that the system forms a dynamic equilibrium. How can an equilibrium system contain small & unchanging amounts of products yet have large amounts of reactants? At this point, your work involves algebra only. Sara Ross. In this way the second equilibrium condition is, Selecting the +y+y-direction to be parallel to FS,FS, the first equilibrium condition for the stick is, Substituting the forces, the first equilibrium condition becomes, We solve these equations simultaneously for the unknown values m3m3 and FS.FS. a. the system will try to minimize the effect of the added CO by consuming more reactants forming more products. Explain the difference between a homogeneous equilibrium & a heterogeneous equilibria? Catalysts would speed up both forward and backward reaction Now we generalize this strategy in a list of steps to follow when solving static equilibrium problems for extended rigid bodies. (a) Geometry and (b) free-body diagram for the door. What is the SI unit of acceleration Class 9? Solution: A We must first find the initial concentrations of the substances present. Here, you should also leave out the concentration of water. Ksp = 1.8 x 10^-10 (a) Choose the, Set up the equations of equilibrium for the object. See more. Check out Equilibrium Constants to find out how to work them out. The first equilibrium condition, Equation 12.2.2, is the equilibrium condition for forces, which we encountered when studying applications of Newtons laws. WebQ: Describe an equilibrium in everyday life that illustrates astate of balance between two opposing A: The boiling water in a closed system. If you mix these products together, nothing will happen - there will be no further reaction. We then divide the product value by the reactant value to find Kc. We use an iron catalyst to increase the overall rate of reaction. Equation 12.23 is the second equilibrium condition (for torques) for the forearm. 14 The Wikipedia defines equilibrium as the condition of a system in which competing influences are balanced. The Assume that the volume of the reaction vessel does not change. At the same time, some of C and D will start reacting to reform A and B. How does Le Chatlier's principle describe an equlilibrium's response to a stress? Shifting the position of the equilibrium to the right means that the equilibrium favours ______. This means that a higher pressure favours the forward reaction and increases the yield of ethanol. You were asked: Identify how Le Chatelier's principle would impact these examples. The semicircular canals and the otolith organs are filled with fluid. a is the molar ratio of A. of the users don't pass the Chemical Equilibrium quiz! Before opening the bottle, the gaseous carbon dioxide and the aqueous carbon dioxide are balanced by the dynamic equilibrium. If they do not, then use the previous steps to track back a mistake to its origin and correct it. The key word here is uniform. We know from our previous studies that the CM of a uniform stick is located at its midpoint, so this is where we attach the weight w, at the 50-cm mark. Show answer Answer As soon as the bottle seal opened, the gaseous carbon dioxide dissolved in liquid carbon dioxide and spilt out of the bottle with bubbles. Note that setting up a free-body diagram for a rigid-body equilibrium problem is the most important component in the solution process. But some reactions are reversible. At this point, we do not need to convert inches into SI units, because as long as these units are consistent in Equation 12.23, they cancel out. Equal balance between any powers, influences, etc. This is called shifting the position of the equilibrium. Because it is simply a ratio of concentrations. As long as the angle in Equation 12.10 is correctly identifiedwith the help of a free-body diagramas the angle measured counterclockwise from the direction of the lever arm to the direction of the force vector, Equation 12.10 gives both the magnitude and the sense of the torque. WebDynamic Equilibrium can be defined as the state of a given system in which the reversible reaction taking place in it stops changing the ratio of reactants and products, but there is a movement of substances between the reactants and the products. b. decreasing temp= right And there could be a variety of examples here. As an example of this in real life, think about a saucepan of water that you are heating to boil some potatoes. Find Kc. We show reversible reactions using half arrows: . There are many examples of systems at equilibrium. the equilibrium will shift on the left and Keq is lowered, Changing the volume of the system alters the equlibrium position of this equilibrium, N2(g) + 3H2(g) 2NH3(g), but a similar change has no effect on this equilibrium H2(g) + Cl2(g) 2HCl(g). Calculate the equilibrium constant of hydrogen when [CO2]= .320 mol/L, [H2O]= .240 mol/L, and [CO]= .280 mol/L, [H2]= [H2O][CO]/Keq[CO2] If you are redistributing all or part of this book in a print format, Be perfectly prepared on time with an individual plan. You put the reactants together, supply them with enough energy and provide just the right conditions, and they react to form new products. Partial pressure is the pressure a gas would exert if it occupied a container by itself. 3. [NO]2]= Keq[O2][N2] Hence, reactants are highly favored compared to products. Why is the concentration of a solid not included as part of the solubility product constant? Identify the questions you need to answer. You'll also be able to have a go at some more examples. Homeostasis keeps our body temperature nearly constant. Pure water has the density of 1.00g/ml at 297 . A 50-kg person stands 1.5 m away from one end of a uniform 6.0-m-long scaffold of mass 70.0 kg. Household size. No acceleration implies constant velocity. Many industrial equilibrium reactions use, Equilibrium constants compare the amount of products to the amount of reactants in a system at equilibrium. CO(g) + 2H2(g) CH3OH(g) + heat Figures throughout this module illustrate various examples. How would decreasing the volume of the reaction vessel affect these equilibria? WebIn the human body, equilibrium plays a prominent role in regulating the concentrations of various substances, notably pH, in the bloodstream. Cules son las dos caractersticas de un equilibrio dinmico? This means a lower temperature favours the forward reaction and increases the yield of ethanol. The ladder in this example is not rotating at all but firmly stands on the floor; nonetheless, its contact point with the floor is a good choice for the pivot. This has to do w/ thermodynamics of solutions. The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. Instead, the ethanol is removed as it is formed, decreasing its concentration and therefore favouring the forward reaction. a. adding CO to the system Up until 1803, scientists believed that all reactions were irreversible. Supplement. Therapists trained in balance problems design a customized program of balance retraining and exercises. Kw, Ka, and Kb are equilibrium constants that involve the dissociation of molecules into ions in solution. Household size. Nie wieder prokastinieren mit unseren Lernerinnerungen. What is the point of equilibrium. The net force on the ladder at the contact point with the floor is the vector sum of the normal reaction from the floor and the static friction forces: We should emphasize here two general observations of practical use. Does a precipitate form? b. Keq= [NbCl3][NbCl5]/[NbCl4]2 If we shift the equilibrium to the right, we say the equilibrium favours the forward reaction. Even processes occur when you wake up, all your daily activities like drinking water, taking a shower, cooking your food, cleaning your car, laughing or crying are guided by different chemical processes. Create the most beautiful study materials using our templates. Calculate Keq for the following equilibrium when [SO3] = 0.0160 mol/L, [SO2] = 0.00560 mol/L, and [O2] = 0.00210 mol/L, Keq= (.0056mol/L)(0.0021mol/L)/(0.016mol/L). N2(g) + O2(g) 2NO(g) When an equilibrium shifts towards the reactants in response to a stress, how is the equilibrium position changed? It is also essential to our sense of balance: the organ of balance (. Transition Metal Ions in Aqueous Solution, Variable Oxidation State of Transition Elements, Intramolecular Force and Potential Energy, Prediction of Element Properties Based on Periodic Trends, Reaction Quotient and Le Chatelier's Principle. what are some everyday examples of equilibrium web mar 25 2020 some everyday examples of equilibrium include a car at rest at a stop sign It might look a little complicated - but don't worry, we'll talk through it in just a second: For the reaction aA + bB cC + dD, Kc = [C] eqmc [D] eqmd[A] eqma [B] eqmb. An equilibrium constant that uses equilibrium partial pressures. # of moles= 1076.6g Mn (1 mol/54.94g)= 19.596 What happens when a body is in equilibrium? Explain your reasoning and show your calculations. Official textbook answer. To calculate Kc, divide the product value by the reactant value. So an object with constant velocity is in equilibrium. We know that a body is said to be in equilibrium. But cooling the egg - say, by freezing it - wont turn it back into its raw, liquid form. 2. a state of chemical balance in the body, reached when the tissues contain the proper proportions of various salts and water. a state in which the rate of forward reaction is equal to the rate of backward reaction. The volume will increase in pressure, it shall shift the reaction equilibrium towards the side w/a smaller total # of particles. Can a nuclear winter reverse global warming?
