The catalyst used in the manufacturing of sulphuric acid by contact process is:

A$$Al_{2}{O}_{3}$$
B$$Cr_{2}{O}_{3}$$
C$$V_{2}{O}_{5}$$
Correct Answer
D$$Mn_{3}{O}_{4}$$

Solution

$$ \mathrm SO_{2}+\dfrac{1}{2}O_{2} \underset{400-450K}{\overset{V_{2}O_{5}}{\longrightarrow}}SO_{3}\overset{H_{2}O}{\longrightarrow} H_{2}SO_{4}$$

The given reaction is a contact process. Here, $$V_{2}O_{5}$$ acts as a catalyst.

Option C is correct.
