Question

The catalyst used in the contact process is-

• A. A. Copper
• B. B. Iron
• C. C. Vanadium pentoxide
• D. D. Manganese dioxide

Answer 1

The correct option is C

C. Vanadium pentoxide

Explanation of Correct Option - Option (C)

1. The contact process is done for the industrial preparation of Sulfuric acid.
2. And the catalyst used for this process is Vanadium pentoxide(${\mathit{V}}_{\mathbf{2}}{\mathit{O}}_{\mathbf{5}}$).
3. So this option is correct.

Incorrect options explanation- Option A,B,D

1. A- Copper- As Vanadium peroxide is used as a. Catalyst in the contact process, this option is incorrect.
2. B- Iron- As Vanadium peroxide is used as a. Catalyst in the contact process, this option is incorrect.
3. D- Magnesium dioxide- As Vanadium peroxide is used as a. Catalyst in the contact process, this option is incorrect.

Hence, option C is correct, as the catalyst required in the contact process is Vanadium pentaoxide.
