Which one is an example of heterogenous catalysis? Hydrolysis of sugar catalysed by ions. Decomposition of ozone is presence of nitrogen monoxide. Combination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron. Oxidation of sulphur dioxide into sulphur trioxide in the presence of oxides of nitrogen.
Multiple Choice Options
- A Hydrolysis of sugar catalysed by H + ions.
- B Decomposition of ozone is presence of nitrogen monoxide.
- C Combination between dinitrogen and dihydrogen to form ammonia in the presence of finely divided iron.
- D Oxidation of sulphur dioxide into sulphur trioxide in the presence of oxides of nitrogen.
Step-by-Step Verified Solution
(1) C 12 H 22 O 11 (aq) + H 2 O _ H + C 6 H 12 O 6 ( aq) + C 6 H 12 O 6 ( aq ) (Homogeneous reaction)
(2) 2 O 3 ( g ) _ NO ( g ) 3 O 2 ( g ) (Homogeneous reaction)
(3) N 2 ( g ) + 3 H 2 ( g ) _ Fe ( s ) 2 NH 3 ( g ) (Reactants and catalyst are in different phase) It is heterogeneous reaction
(4) SO 2 ( g ) + 1 2 O 2 ( g ) _ NO ( g ) SO 3 ( g )
