Question

Which one is an example of heterogenous catalysis?

A

Oxidation of sulphur dioxide into sulphur trioxide in the presence of oxides of nitrogen

B

Hydrolysis of sugar catalysed by H+^+ ions

C

Decomposition of ozone in presence of nitrogen monoxide

D

Combination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron

Step-by-Step Solution

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. In the Haber process (option D), the reactants (N2_2 and H2_2 gases) are in the gas phase, while the catalyst (iron) is a solid. The other options involve homogeneous catalysis where the catalyst and reactants are in the same phase.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from General. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
