One reaction involved in the conversion of iron ore to the metal is FeO(s) + CO(g) → Fe(s) + CO2(g) Use Hess’s Law to calculate ΔHrxn given the following. 3 Fe2O3(s) + CO(g) → 2 Fe3O4(s) + CO2(g) ΔH = −47.0 k Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g) ΔH = −25.0 k Fe3O4(s) + CO(g) → 3 FeO(s) + CO2(g) ΔH = 19.0 k
