We are asked to calculate ΔH˚rxn for the following reaction: Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g).
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.
Use standard enthalpies of formation to determine ΔH˚rxn for the reaction: Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g).
