1. Reactions that occur in the gaseous state are affected by changing the volume of the container. Which choice best describes what will happen to the reaction if the volume of the container is decreased? The reaction will shift right. The reaction will shift left. The reaction will not change. The reaction will speed up.
Catalysts can speed up the rate at which equilibrium is achieved. As a result. the equilibrium constant is also affected though the position at equilibrium remains the same. A-If the first statement is TRUE and the second statement is FALSE B-If the first statement is FALSE and the second statement is TRUE OC-If both statements are TRUE OD-If both statements are FALSE
Which statement regarding chemical equilibrium is incorrect? A) The concentrations of reactants and products remain constant unless some stress in applied to the system. B) Reactants are being converted to products and products to reactants. C) The concentrations of reactants and products have to be equal at equilibrium. D) The rates of the forward and reverse reactions are equal. E) If more product is added to a system at equilibrium, the reaction will shift to use up some of the added product, thus creating more of the reactant(s), and even though these concentrations are changing, the equilibrium constant, K, doesn’t change as long as the temperature remains the same.
