Compute for the total entropy change (∆Suniv) in the oxidation of metallic iron into ferric oxide (Fe2O3) under standard conditions. Determine the spontaneity of the process at these conditions. (the ∆Hf°for elemental substance is zero and that for Fe2O3 is -824.2 kJ/mol) 4Fe(s) + 3 O2(g) → 2Fe2O3 (s)
