Oxygen (O2) is a reactant in the Contact Process. It reacts with sulfur dioxide (SO2) to produce sulfur trioxide (SO3). The overall reaction is:
SO2(g) + ½O2(g) → SO3(g)
If the supply of oxygen was insufficient, the reaction would not proceed efficiently. The amount of SO3 produced would be limited by the amount of oxygen available. This would result in a lower yield of sulfuric acid and a slower reaction rate. The process might even stall completely if there is no oxygen.
