Question

In a reversible reaction, catalyst:

• A. increases the rate of the forward reaction.
• B. decreases the rate of the backward reaction
• C. increases the rates of forward and backward reactions equally
• D. alters the equilirium constant of the reaction

Answer 1

Answer: (C)

increases the rates of forward and backward reactions equally

The role of a catalyst in a reversible reaction is to allow the equilibrium to be achieved quickly.

A catalyst increases the rate of forward and reverse reaction to an equal extent. However, it does not affect the value of the equilibrium constant.

Hence, the correct option is $\text{C}$
