Which of the following statements is (are) true? Correct the false statement (s). When a reactant is added to a system at equilibrium at a given temperature, the reaction will shift right to reestablish equilibrium. When a product is added to a system at equilibrium at a given temperature, the value of for the reaction will increase when equilibrium is reestablished. When temperature is increased for a reaction at equilibrium, the value of for the reaction will increase. When the volume of a reaction container is increased for a system at equilibrium at a given temperature, the reaction will shift left to reestablish equilibrium. Addition of a catalyst (a substance that increases the speed of the reaction) has no effect on the equilibrium position.

When a reactant is added to a system at equilibrium at a given temperature, the reaction will shift right to reestablish equilibrium. True

When a product is added to a system at equilibrium at a given temperature, the value of for the reaction will increase when equilibrium is reestablished. False, the value of the equilibrium constant is not changed by changing concentration of species in the equilibrium.

When temperature is increased for a reaction at equilibrium, the value of for the reaction will increase. True for an endothermic reaction but false for an exothermic reaction.

When the volume of a reaction container is increased for a system at equilibrium at a given temperature, the reaction will shift left to reestablish equilibrium. if reactants have more moles of gas then the statement is true but false if the products have more moles of gas.

Addition of a catalyst (a substance that increases the speed of the reaction) has no effect on the equilibrium position. True
