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 $S O_{3} (g)$ .

Q. The following flow diagram shows the main steps for the manufacture of sulphuric acid by the Contact Process.

(a) Name a substance other than sulphur that would react with dry air on heating to form sulphur dioxide.
(b) Write the equation for the reaction taking place in the catalytic converter.
(c) The sulphur trioxide is absorbed in

98 %

sulphuric acid and not in water. Give a reason for this and write the equation taking place here.
(d) What is added to change oleum into sulphuric acid?

Q. (a) Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide in step C.
(b) In the Contact process for the manufacture of the sulphuric acid, sulphur trioxide is not converted to sulphuric acid by reacting it with water. Instead, a two-steps procedure is used. Write the equations for the two steps involved in D.
