Calculate the standard enthalpy change (∆H°) and standard entropy change (∆S°) for the reaction between solid aluminum and gaseous oxygen to form solid aluminum oxide, given the following balanced chemical equation:4Al(s) + 3O2(g) → 2Al2O3(s) The standard enthalpies of formation of Al(s), O2(g), and Al2O3(s) are -394.4 kJ/mol, 0 kJ/mol, and -1675.7 kJ/mol, respectively. The standard entropy change for the reaction of O2(g) to form Al2O3(s) is -159.6 J/K·mol.
