प्रश्न
With the help of equations, give an outline for the manufacture of sulphuric acid by the contact process.
उत्तर
Formation of sulphur dioxide :
S + O2 → SO2
Conversion of SO2 to SO3
\[\ce{2SO2 + O2 ⇌[V2O3][400-450°C] 2SO3}\]
Conversion of sulphur trioxide to oleum:
SO3 + H2SO4 → H2S2O7
Dilution of oleum:
H2S2O7 + H2O → 2H2SO4
