InterviewSolution

1.	What is the catalyst used for oxidation of `SO_(2)` to `SO_(3)` in lead chamber process for manufacture of sulphuric acid ?A. Nitric oxideB. Nitrous oxideC. Potassium iodideD. Dilute HCl
Answer» Correct Answer - 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])`
