What is the catalyst used for oxidation of `SO_(2)` to `SO_(3)` in lead chamber process for manufacture of sulphuric acid ?

A

Nitric oxide

B

Nitrous oxide

C

Potassium iodide

D

Dilute HCl

Text Solution

Verified by Experts

The correct Answer is:
A
In lead chambar process, a mixture containning `SO_(2)`, air NO is treated with steam `(H_(2)O)`.
In this reaction, NO (nitric oxide) act as a catalyst.
`2SO_(2)^(+)underset("(From air)")(O_(2))+2H_(2)O+underset("Catalyst")([NO])to2H_(2)SO_(4)+underset("Catalyst")([NO])`
