In the Mond process for the purification of nickel, carbon monoxide is reacted with heated nickel to produce Ni(CO)4, which is a gas and can therefore be separated from solid impurities:
Ni(s) + 4CO(g) ⇌ Ni(CO)4(g)
Given that the standard free energies of formation of CO(g) and Ni(CO)4(g) are −137.3 and −587.4 kJ/mol, respectively,
calculate the equilibrium constant of the reaction at 86.0°C.
Assume that ΔG o f is temperature-independent.
