Question

State the conditions required for the following reactions to take place:

The conversion of sulphur dioxide to sulphur trioxide.

Answer 1

The conditions for the conversion of \[\ce{SO2}\] to \[\ce{SO3}\]

1. The reaction is exothermic, so reactions are favoured at low temperatures.
2. High pressure favours the reaction because the product formed has less volume than the reactant.
3. Excess of oxygen.
4. A suitable catalyst like platinum.
