Solution

The correct option is B X: $V_{2} O_{5}$ ; Y: $400^{o} C$
The process of oxidation of sulphur dioxide to sulphur trioxide is a reversible reaction.Therefore to obtain better yields, the reaction is performed in a favourable conditions.

So, the reaction is performed at $400^{o} C$ temperature and high pressure in presence of a suitable catalyst like platinum or vanadium pentoxide.

Q. What is the density of SO₂ gas at 27 degree Celsius and 2 ATM pressure.

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 $S O_{3} (g)$ .
