Vedclass · Answer

(A) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. It works by providing an alternative reaction pathway or mechanism that has a lower activation energy $(E_a)$. Therefore,the statement that it does not change the activation energy is incorrect. Catalysts often form temporary intermediate complexes with reactants to facilitate the reaction,and enzyme catalysis is known for being highly specific.
