Utilize the standard enthalpies of formation from Appendix II (A-7 to A-12) to compute the enthalpy change (in kJ) for the reduction of iron (III) oxide to iron at 298 K and 1 atm. Compute it for the reaction as written, namely 2 moles of iron (III) oxide and 3 moles of carbon.
2Fe2O3(s) + 3C(s) --> 4Fe(s) + 3CO2(g)
