Question

A homogeneous catalytic process among the following is

• A. Haber’s process of manufacturing of ammonia
• B. Contact process of manufacturing sulphuric acid
• C. Ostwald’s process of manufacturing nitric acid
• D. Lead chamber process of manufacturing sulphuric acid

Answer 1

Answer: (D)

Haber’s process : $N{H}_3$ is manufactured from $N_2$ and $H_2$ using Fe as catalyst (heterogeneous catalysis)
Contact process: In the manufacture of $H_{2}S{O}_4$, $S{O}_2$ is oxidised to $S{O}_3$ using platinised asbestos or $V_2{O}_5$ as catalyst (heterogeneous catalysis).
Ostwald process : In the manufacture of $HN{O}_3$ $N{H}_3$ is oxidised to $NO$ using $Pt$ as catalyst (heterogeneous catalysis).
Lead chamber process : $S{O}_2$ is oxidised to $S{O}_3$ in the presence of $NO$ as catalyst (homogeneous catalysis)
