Q. Which of the following is an example for heterogeneous catalysis reaction?
A) $2{SO}_{2}(g) + O_{2}(g)\overset{NO\ (g)}{\rightarrow}2{SO}_{3}(g)$
B) Hydrolysis of aqueous sucrose solution in the presence of aqueous mineral acid
C) $2H_{2}O_{2}(l)\overset{pt(s)}{\rightarrow}2H_{2}O(l) + O_{2}(g)$
D) Hydrolysis of liquid in the presence of aqueous mineral acid
Explanation
(d)
$CO(g) + 2H_{2}(g)\overset{Cu,\ ZnO - {Cr}_{2}O_{3}(s)}{\rightarrow}{CH}_{3}OH(l)$
In this reaction, reactants and catalyst are in different physical states, hence it is an example of heterogeneous catalysis.
