Vedclass · Answer

(C) catalyst is a substance that increases the rate of a reaction without itself undergoing any permanent chemical change.
It works by providing an alternative reaction pathway with a lower activation energy $(E_a)$.
Since the catalyst lowers the activation energy for both the forward and backward reactions to the same extent,it does not change the overall enthalpy change $(\Delta H)$ of the reaction.
Option $C$ is incorrect because a catalyst decreases the activation energy for both the forward and backward reactions,not just the forward reaction.
