27. Use the ΔH°f information provided to calculate ΔH°rxn for the following?

ΔH°f (kJ/mol) SO2Cl2(g) + 2 H2O(l) → 2 HCl(g) + H2SO4(l) ΔH°rxn = ?

SO2Cl2(g) -364

H2O(l) -286

HCl(g) -92

H2SO4(l) -814

    ΔH°rxn = ΔH°f n* Products - ΔH°f n* Reactants

    n =coefficient

    ΔH°rxn = ((-814 + 2(-92)) - ((-364 + 2(-286))

    ΔH°rxn = -62 kJ/mol
