Verified by Experts

The correct answer is:

Uncatalysed oxidation of sulphur dioxide is slow.

However, the presence of particulate matter in polluted air catalyzes the oxidation of SO 2 to SO 3 .

SO 2 (g) + O 2 (g) 2SO 3 (g)

This reaction can also be promoted by O 3 and H 2 O 2 , as,

SO 2 (g)+O 3 (g) SO 3 (g) + O 2 (g)

SO 2 (g) + H 2 O 2 (l) H 2 SO 4 (aq)
