When exposed to UV light, phosgene decomposes according to the reaction COCl2 (g) → CO (g) + Cl2 (g) All the air is removed from a flask. The flask is then filled with phosgene to a pressure of 1.0 atm.  The flask is sealed and exposed to UV light so the phosgene decomposes.  The temperature remains constant during the decomposition.   (a) What are the partial pressures of the CO and Cl2 after the decomposition of phosgene is complete? (answer: 1 atm each) (b) What is the total pressure in the flask after the decomposition of phosgene is complete? (answer: 2 atm)
