In the manufacture of H2SO4, the reaction:
H2O + SO3 → H2SO4 is not used because it is highly exothermic.
Instead, the SO3 is dissolved in conc H2SO4 to form a substance called oleum, H2S2O7. This is then dissolved in water to produce H2SO4
H2S2O7 + H2O → 2H2SO44 This is a much more controllable reaction.
