Sulfuric acid comes from the oxidation of sulfur. The stages of the reactions are given below: S + O2 --> SO2 ?H= -296.8 kj SO2 + 1/2 O2 --> SO3 ?H= -98.9 kj SO3 + H2O --> H2SO4 ?H= -130.0 kj The typical plant produces 750 tons of H2SO4 per day. Calculate amount of heat produced by the plant per day.
