Phosgene was used as a poisonous gas in World War I. At high temperatures it decomposes as follows:

with Kc = 4.6 × 103 at 800 K.
a. A sample of 6.55 g of COCl2 is placed in a 1.00-L reaction vessel and heated to 800 K. What are the equilibrium concentrations of all of the species?
b. What fraction of COCl2 has decomposed?
c. If 3 g of carbon monoxide is inserted into the reaction vessel, what qualitative effect would this have on the fraction of COCl2 that has decomposed?
