Impure nickel, refined by smelting sulfide ores in a blast furnace, can be converted into metal from 99.90% to 99.99% purity by the Mond process. The primary reaction involved in the Mond process is: Ni(s) + 4CO(g) = Ni(CO)4(g) For Ni(CO) (g) the AH° = 607 kJ/mol and Sº - 417 J/K mol J/ Kmol, for CO(g) the AH = -110.5 kJ/mol and Sº = 198 J/K mol, and for Ni(s) the Sº = 30.0 J/K.mol at 298 K. The first step of the Mond process involves equilibrating impure nickel with and at about 50°C. The purpose of this step is to convert as much nickel as possible into the gas phase. Calculate the equilibrium constant for the above reaction at 50°C.     Equilibrium constant , K = 5.84 ×107
