Calculate the standard enthalpy and standard entropy change at 298 K for the following reaction: 2Fe(s) + 3/2O2(g) → Fe2O3(s) Given that the standard enthalpies of formation for Fe(s), O2(g), and Fe2O3(s) are 0 kJ/mol, 0 kJ/mol, and -826 kJ/mol respectively. Also, the standard molar entropy of Fe2O3(s) is 87.4 J/K/mol.
