Question

Which of the following statements is False about catalyst?
a. Catalyst increases the rate of reverse reactions.
b. Since the catalyst increases rates of the reaction, equilibrium constant also increases.
c. Catalyst lowers the activation barrier between reactants and products.
d. Catalyst increases the rate of forward reactions.

Answer 1

Answer:

B.

Explanation:

The equilibrium constant is a ratio of products to reactants at equilibrium. An increase of the equilibrium constant would mean that the products are increasing in the reaction vessel at the expense of the reactants. That is not what a catalyst does. A catalyst ensures that equilibrium is reached faster. It does not favour the backward or forward reaction
