MHT CET 2026 Chemistry question

What is the role of catalyst in reaction ?

(A)To increase activation energy of a reaction
(B)To decrease the equilibrium constant of the reaction
(C)To supply energy to the reactants
(D)To decrease activation energy of a reactionCorrect

Answer: (D)

Solution

A catalyst provides an alternative reaction path (mechanism) with a lower activation energy , so a larger fraction of molecules has sufficient energy and the rate increases (). Hence option (D). (A) is the opposite
