A) Manufacture of sulphuric acid by Contact process
B) Manufacture of ammonia by Habefs process
C) Hydrolysis of sucrose in presence of dilute hydrochloric acid
D) Hydrogenation of oil
Correct Answer: C
Solution :
In homogeneous catalysis, reactants and catalyst are in the same phase. [a] \[S{{O}_{2}}(g)+{{O}_{2}}(g)S{{O}_{3}}(g)\] (Contact process) It is an example of heterogeneous catalysis. [b] \[{{N}_{2}}(g)+{{H}_{2}}(g)2N{{H}_{3}}(g)\] (Habefs process) It is an example of heterogeneous catalysis. [c] \[{{C}_{12}}{{H}_{22}}{{O}_{11}}(aq)+{{H}_{2}}O(aq){{C}_{6}}{{H}_{12}}{{O}_{6}}\] \[+{{C}_{6}}{{H}_{12}}{{O}_{6}}\] Thus, it is also an example of heterogeneous catalysis.
