JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Which of the following is an example for heterogeneous catalysis reaction?

(A)
(B)Hydrolysis of aqueous sucrose solution in the presence of aqueous mineral acid
(C)Correct
(D)Hydrolysis of methyl acetate in the presence of dilute hydrochloric acid

Answer: (C)

Solution

In option (A) the catalyst NO is a gas, in the same phase as the gaseous reactants, so it is homogeneous catalysis; options (B) and (D) both describe acid-catalysed ester/sugar hydrolysis with the mineral acid dissolved in the same aqueous/liquid phase as the substrate, which is
