Consider this equation for the heated decomposition of potassium chlorate: 2KClO↓3(s) > 2KCl(s) + 3O↓2(g), ΔH = ?

Given these enthalpy of formation values:

KClO3: ΔHf = -391kJ/mol; KCl: ΔHf = -433kJ/mol

Calculate the enthalpy of the above reaction in kilojoules per mole of reactant.
Reference: ΔH = sum(HΔproducts) - sum(ΔHreactants)
