We can use the following equation to solve for ΔH˚rxn:
Note that we need to multiply each ΔH˚f by the stoichiometric coefficient since ΔH˚f is in kJ/mol.
Also, note that ΔH˚f for elements in their standard state is 0.
Reaction: SO3(g) + H2O(l) → H2SO4(aq)
Element/ Compound Standard Heat of Formation (kJ/mol)
Calculate ΔH° for each of the following reactions, which occur in the atmosphere.
(b) SO3(g) + H2O(l) → H2SO4(aq)
