Q. 65 - Termoquímica / Lista Plataforma Assaad

In the production of metallic iron, Fe(s), ferrous oxide FeO(s) is reduced by the action of carbon monoxide CO(g), according to the reaction: FeO(s) + CO(g) → Fe(s) + CO2(g) Given that the enthalpy change of this process is unknown, use the following thermochemical equations and Hess's Law to determine the approximate value of ΔH:
