MHT CET 2026 Chemistry question

What is the role of catalyst in catalytic reaction ?

(A)It decreases the enthalpy of reaction
(B)It increases the enthalpy of reaction.
(C)It decreases the energy of activation of reaction.Correct
(D)It increases the energy of activation of reaction.

Answer: (C)

Solution

A catalyst provides an alternative reaction pathway (a different mechanism) with a lower activation energy . A lower increases the fraction of molecules with sufficient energy, and by the Arrhenius equation the rate constant and hence
