Question

Few reactions of industrial importance are listed below. Which of the following catalysts is not correctly matched with the reaction?

• A. Haber's process : Finely divided $Fe+Mo$ as promoter
• B. Contact process : $V_2{O}_5$
• C. Ostwalds process : $F{e}_2{O}_3$
• D. None of these

Answer 1

The correct option is C Ostwalds process : $F{e}_2{O}_3$

• Substances, which accelerate the rate of a chemical reaction and themselves remain chemically and quantitatively unchanged after the reaction, are known as catalysts.
• In Haber's process for manufacturing of $N{H}_3$, $Fe$, and $Mo$ are used as catalyst and promoter respectively.
• In contact process of manufacturing Sulfuric acid $V_2{O}_5$, may also be used as a catalyst.
• Platinised asbestos is used as a catalyst for Ostwald's process for the manufacture of nitric acid.
• Hence, $F{e}_2{O}_3$ is not used in Ostwald's process and hence it is the correct answer.
