A Catalyst is a substance which accelerates the rate of a chemical reaction without undergoing any change in its chemical composition or mass during the reaction.

A catalyst accelerates the rate of a reaction by lowering the activation energy.

Catalyst provides alternate pathway for reaction. Also, it increases the rate of backward and forward reaction to same extent. (as shown)

Due to this lower activation energy, equilibrium attains faster.
