Q. In a reversible reaction, the catalyst

A) Increases the activation energy of the backward reaction
B) Increases the activation energy of the forward reaction
C) Decreases the activation energy of both forward and backward reaction
D) Decreases the activation energy of forward reaction
Explanation

(c)
A catalyst increases the rate of reaction by decreasing its activation energy. In a reversible reaction, catalyst decreases activation energies of both, forward and backward reactions, equally, thereby increasing rate of both reactions equally. Thus, equilibrium is approached quickly.
