When a catalyst is used an equilibrium process,

A

it increases the rate of forward reaction

B

it decreases the rate of backward reaction

C

it decreases activation energy of forward process and decreases activation energy of backward process

D

it fastens the attainment of equilibrium by lowering activation energy.

Text Solution

Verified by Experts

The correct Answer is:
D
The equilibrium is attained faster in case of reaction in which catalyst is used as it lowers the activation energy.
