Answer
(a) Contact process
(b) Sulphuric acid has a great affinity for water. It readily removes elements of water from other compounds. Hence, it is used as a dehydrating agent.
(c) Concentrated sulphuric acid as an Oxidising agent:
Cu + 2H2SO4 [conc.] ⟶ CuSO4 + 2H2O + 2SO2 ↑
Concentrated sulphuric acid as a non-volatile acid:
NaNO3 + H2SO4 [conc.] NaHSO4 + HNO3
