Activation energy of the reaction remains unaltered.

Vedclass · Answer

(D) catalyst is a substance that increases the rate of a chemical reaction by providing an alternative pathway with a lower activation energy $(E_a)$.$1$. It does not alter the Gibbs energy $(\Delta G)$ of the reaction.$2$. It does not change the equilibrium position because it accelerates both the forward and backward reactions to the same extent.$3$. Since it provides a new pathway with lower activation energy,the activation energy of the reaction is indeed altered (lowered).Therefore,the statement that the activation energy remains unaltered is incorrect.
