Phosgene decomposes according to the following reaction:  COCl2(g) ⇌ CO(g) + Cl2(g)  If the reaction mixture initially contains [x] M COCl2, calculate the equilibrium concentration of CO if K c for the reaction at this temperature is [y] × 10 -4. Report your answer in scientific notation with the correct number of significant figures and the correct units.  You can use scientific/exponential notation to represent numeric values. Eg., -0.0001 can be written as 1.0e-4 or as 1.0E-4. Spaces are not allowed.
