A sulfuric acid plant produces a considerable amount of heat. This heat is used to generate electricity, which helps reduce operating costs. The synthesis of H2SO4 consists of three main chemical processes: (1) oxidation of S to SO2, (2) oxidation of SO2 to SO3, (3) the dissolving of SO3 in H2SO4 and its reaction with water to form H2SO4. If the third process produces 130kJ/mol, how much heat is produced in preparing a mole of H2SO4 from a mole of S? How much heat is produced in preparing 5000 pounds of H2SO4?
