2) Lexan is made up of phosgene(COCl2) a poisonous gas. Phosgene decomposes by the equation on the board. If pure phosgene at an initial pressure of 1.0atm decomposes, calculate the equilibrium position.
A 1.0 liter vessel was initially filled with pure NOBr, at a pressure of 4.0atm (at 300K). After equilibrium, was established, the partial pressure of NOBr was 2.5atm. What is Kp for this reaction.
a) 0.45 b) 0.27 c) 0.18 d) 0.75
