Nickel and carbon monoxide react to form nickel carbonyl, like this:
Ni(s) + 4 CO(g) → Ni(CO)4(g)
At a certain temperature, a chemist finds that a 7.2 L reaction vessel containing a mixture of nickel, carbon monoxide, and nickel carbonyl at equilibrium has the following composition:
Calculate the value of the equilibrium constant Kc for this reaction. Round your answer to 2 significant digits.
