Calculate ΔG° for each of the following reactions from the equilibrium constant at the temperature given.
(a) Cl2(g) + Br2(g) ⟶ 2BrCl(g) T = 25 °C Kp = 4.7 × 10−2
(b) 2SO2(g) + O2(g) ⇌ 2SO3(g) T = 500 °C Kp = 48.2
(c) H2 O(l) ⇌ H2 O(g) T = 60 °C Kp = 0.196 atm
(d) CoO(s) + CO(g) ⇌ Co(s) + CO2(g) T = 550 °C Kp = 4.90 × 102
(e) CH3 NH2(aq) + H2 O(l) ⟶ CH3 NH3+(aq) + OH−(aq) T = 25 °C Kp = 4.4 × 10−4
(f) PbI2(s) ⟶ Pb2+(aq) + 2I−(aq) T = 25 °C Kp = 8.7 × 10−9
