Which one is an example of heterogenous catalysis?
Which one is an example of heterogenous catalysis?
Options
- ACombination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron.
- BOxidation of sulphur dioxide into sulphur trioxide in the presence of oxides of nitrogen.
- CHydrolysis of sugar catalysed by ions.
- DDecomposition of ozone in presence of nitrogen monoxide.
Correct answer
A. Combination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron.
Step-by-step solution
Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. Combination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron is a heterogenous catalysis because iron is solid catalyst and reactants and products are gases.
