Sulfur is oxidized to sulfur dioxide by atmospheric oxygen.
Sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water.
Sulfur dioxide is oxidized to sulfur trioxide in the following sequence of reactions: $$2 \mathrm{SO}_{2}(g)+2 \mathrm{NO}_{2}(g) \longrightarrow 2 \mathrm{SO}_{3}(g)+2 \mathrm{NO}(g)$$ $$2 \mathrm{NO}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{NO}_{2}(g)$$ (a) Write the chemical equation for the overall reaction. (b) Identify any molecule that acts as a catalyst or intermediate in this reaction.
