Which one is an example of heterogenous catalysis?
- AOxidation of sulphur dioxide into sulphur trioxide in the presence of oxides of nitrogen
- BHydrolysis of sugar catalysed by ions
- CDecomposition of ozone in presence of nitrogen monoxide
- DCombination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron
Solution & Step-by-step Explanation
Heterogeneous catalysis is a process where the reactant and the catalyst are in different phases.Options A, B, and C involve reactants and catalysts in the same phase (gas/gas or liquid/liquid).Option D (Haber's Process): Nitrogen () and Hydrogen () react on the surface of solid Iron (). Since the reactants are gaseous and the catalyst is solid, it is heterogeneous catalysis.
