Question

e Incorrect Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. Nickel carbonyl decomposes to form nickel and carbon monoxide, like this: Ni(CO)4(9) Ni(s)+4 CO(9) At a certain temperature, a chemist finds that a 7.8 L reaction vessel containing a mixture of nickel carbonyl, nickel, and carbon monoxide at equilibrium has the following composition: compound Ni(CO)4 Ni amount 0.288 g 89.3 g CO 1.07 g Calculate the value of the equilibrium constant K, for this reaction. Round your answer to 2 significant digits. K = 4.5 x 10-21 X 5 ?
