Sulfur dioxide reacts with oxygen in the presence of platinum to give sulfur trioxide.

2SO2(g)+O2(g).------>2SO3(g).

☑The Oxygen (O2) and the Sulfur Dioxide (SO2), in the presence of platinum, form sulfur trioxide (SO3) which will react with water (H2O) to produce sulfuric acid (H2SO4).

☑Though the platinum is not used in the reaction, nor is it affected, it is a catalyst required for the reaction to take place.

SO3 +H2O --> H2SO4
