Lexan is a plastic used to make compact discs, eyeglass lenses and bullet-proof glass. One of the components used to make Lexan is phosgene(COCl2), an extremely poisonous gas. Phosgene decomposes by the equilibrium reaction: COCl2(g)   CO(g)  +  Cl2(g) The Kp of this reaction is 6.8 E-9 at 100C. If pure phosgene at a pressure of 2.5 atm decomposes, calculate the equilibrium pressures of each compound. Prove the 5% rule can be used.
