Question
Determine the free energy change for each of the following reactions, which are run under standard state conditions and 25 °C. Identify each as either spontaneous or nonspontaneous at these conditions.
(a) C(s, graphite) + O2(g) ⟶ CO2(g)
(b) O2(g) + N2(g) ⟶ 2NO(g)
(c) 2Cu(s) + S(g) ⟶ Cu2 S(s)
(d) CaO(s) + H2 O(l) ⟶ Ca(OH)2(s)
(e) Fe2 O3(s) + 3CO(g) ⟶ 2Fe(s) + 3CO2(g)
(f) CaSO4 ·2H2 O(s) ⟶ CaSO4(s) + 2H2 O(g)
