प्रश्न
Write balanced equations for the three chemical reactions that take place during the conversion of sulphur dioxide to sulphuric acid in the contact process. Name the catalyst used in the contact process.
उत्तर
Balanced eqations for the chemical reactions that take place during the conversion of sulphur dioxide to sulphuric acid are :
- 2SO2 + O2 ⇌ 2SO3 + Heat
- SO3 + H2SO4 → H2S2O7
- H2S2O7 + H2O → 2H2SO4
Vanadium pentoxide is used as a catalyst.
