ICE Problem: Calculate Final Concentrations

Phosgene, COCl2 (g), is an extremely toxic gas. It was used during World War I. Today it is used to manufacture pesticides, pharmaceuticals, dyes, and polymers. It is prepared by mixing carbon monoxide and chlorine gas.

CO (g) + Cl2 (g) = COCl2 (g) <-- the equal sign should be the sign for foward and reversible reactions ( arrows facing both ways )

0.055 mol of CO (g) and 0.072 mol of Cl2 (g) are placed in a 5.0 L container. At a certain temperature, the equilibrium constant is 20. What are the equilibrium concentrations of the mixture?
