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 64.0°c. assume that δg o f is temperature-independent.
