Question

Which among the following catalysts is used in manufacture of sulphuric acid by contact process?

• A. Ni
• B. Fe with Mo
• C. V$_2$O$_5$
• D. MnO$_2$

Hint:

Vanadium pentoxide (V$_2$O$_5$) is the catalyst used in the contact process for manufacturing sulfuric acid.

Answer 1

The Correct Option is C

Step 1: Understanding the contact process.
The contact process is used to manufacture sulfuric acid from sulfur dioxide and oxygen. The catalyst used in this process is vanadium pentoxide (V$_2$O$_5$), which speeds up the reaction without being consumed.
Step 2: Analyzing the options.
(A) Ni: Nickel is not used in the contact process for sulfuric acid production.
(B) Fe with Mo: This combination is not used in the contact process.
(C) V$_2$O$_5$: This is the correct catalyst used in the contact process for manufacturing sulfuric acid.
(D) MnO$_2$: Manganese dioxide is not used in this process.
Step 3: Conclusion.
The correct catalyst used in the contact process is (C) V$_2$O$_5$.
