Le Chatelier's Challenge


Le Chatelier's ChallengeVersion en ligne Test your knowledge on Le Chatelier's Principles and equilibrium shifts in chemistry! par Jasmine Villaruel 1 What does Le Chatelier's Principle state about equilibrium? a It shifts to counteract changes in concentration, temperature, or pressure. b It only applies to gas reactions. c It favors the formation of products only. d It remains constant under all conditions. 2 How does increasing pressure affect a gaseous equilibrium? a It shifts towards the side with more moles of gas. b It has no effect on the equilibrium. c It shifts towards the side with fewer moles of gas. d It always favors the reactants. 3 What happens when the temperature of an exothermic reaction is increased? a The equilibrium shifts to the right, favoring products. b There is no shift in equilibrium. c The equilibrium shifts to the left, favoring reactants. d It causes complete conversion to products. 4 Which factor does NOT affect the position of equilibrium? a The presence of a catalyst. b Change in temperature. c Change in concentration of reactants. d Change in pressure. 5 What effect does adding more reactants have on equilibrium? a It causes the reaction to stop. b It shifts the equilibrium to the right, favoring products. c It has no effect on the equilibrium. d It shifts the equilibrium to the left. 6 In a reaction at equilibrium, what does a shift to the right indicate? a Formation of more reactants. b Formation of more products. c Increased energy of the system. d No change in concentrations. 7 What is the effect of decreasing the volume of a gas reaction at equilibrium? a It has no effect on the equilibrium. b It causes the reaction to reverse. c It shifts towards the side with more gas moles. d It shifts towards the side with fewer gas moles. 8 How does a temperature decrease affect an endothermic reaction? a It shifts the equilibrium to the right. b It shifts the equilibrium to the left, favoring reactants. c It increases the rate of reaction. d It has no effect on the equilibrium. 9 What is the primary purpose of Le Chatelier's Principle? a To predict how changes affect chemical equilibria. b To determine reaction rates. c To calculate equilibrium constants. d To identify catalysts. 10 Which of the following changes will NOT shift the equilibrium? a Adding an inert gas at constant volume. b Changing the concentration of reactants. c Changing the temperature. d Changing the pressure.
