Lexan is a plastic used to make compact discs, eyeglass lenses, and bullet-proof glass. One of the compounds used to make Lexan is phosgene (COCl2), an extremely poisonous gas. Phosgene decomposes by the following reaction for which Kp = 6.8 ✕ 10-9 at 100°C. COCl2(g) equilibrium reaction arrow CO(g) + Cl2(g) If pure phosgene at an initial pressure of 2.0 atm decomposes, calculate the equilibrium pressures of all species.
