Q. Give chemical equations to manufacture of Sulphuric Acid by Contact process.

Q. In the contact process for the manufacture of sulphuric acid give equations for the conversion of sulphur trioxide to sulphuric acid.

Sulphur trioxide gas is an important precursor to manufacture sulphuric acid. It is produced by the catalytic oxidation of $S O_{2}$ gas. In the contact process, once we obtain $S O_{3} (g)$ , Sulphuric acid is obtained by the hydrolysis of $S O_{3} (g)$ .
