The Mond process for purifying nickel involves the formation of nickel tetracarbonyl, Ni(CO)4, a volatile liquid, from nickel metal and carbon monoxide. Carbon monoxide is passed over impure nickel to form nickel carbonyl vapor, which, when heated, decomposes and deposits pure nickel.

Write the expression for Kc for this reaction.
