उत्तर
2SO2 + O2 +2H2O`overset("No" )(->)`2H2SO4
The above net reaction can be written as the sum of the following reactions taking place in different steps.
1) 2H2O +NO `rightarrow` HNO3 +3H+
2) S + O2 `rightarrow` SO2 (Oxidation of sulphur)
3) 2HNO3 + 2SO2 `rightarrow` H2O +NO +NO2 +2SO3
Nitric acid or NO2 is used to oxidize SO2 to SO3.
Or SO2 +NO2 `rightarrow` SO3 + NO
4) SO3 +H2O `rightarrow` H2SO4
Sulphur trioxide reacts with water to form H2SO4 .
