The symbol equation for the conversion of sulfur dioxide to sulfur trioxide is:
- 2 SO2(g) + O2(g) ⇌ 2 SO3(g)
A catalyst, typically vanadium(V) oxide (V2O5), is used in the Contact Process to speed up the reaction. It lowers the activation energy required for the reaction to occur, allowing the reaction to proceed at a faster rate at a lower temperature. This is economically beneficial.
