a. When a reactant is added to a system at equilibrium at a given temperature, the reaction will shift right to reestablish equilibrium.
b. When a product is added to a system at equilibrium at a given temperature, the value of K for the reaction will increase when equilibrium is reestablished. Ni catalyst 750° C
c. When temperature is increased for a reaction at equilibrium, the value of K for the reaction will increase.
d. Addition of a catalyst (a substance that increases the speed of the reaction) has no effect on the equilibrium position.
