MHT CET 2026 Chemistry question

What is the role of glycerol in the decomposition of hydrogen peroxide?

(A)It increases the reaction rate.
(B)It reduces the reaction rate.Correct
(C)It increases the enthalpy of the reaction.
(D)It increases the rate of collisions between reactant molecules.

Answer: (B)

Solution

Glycerol (like acetanilide) is a negative catalyst (inhibitor) for the decomposition of , ; it is added to hydrogen peroxide to stabilise it during storage. It lowers the rate of the reaction. Hence (B). (A) and (D)
