(a) Calculate ∆G° and KP for the following equilibrium reaction at 25°C. The ∆G°f values are 0 for Cl2(g), -286 kJ/mol for PCl3(g), and - 325 kJ/mol for PCl5(g).
PCl5(g) ⇌ ΔPCl3(g) + Cl2(g)
(b) Calculate ∆G for the reaction if the partial pressures of the initial mixture are PCl5 0.0029 atm, PCl3 5 0.27 atm, and PCl2 = 0.40 atm.
