1) Consider 1.70 mol of carbon monoxide and 3.00 mol of chlorine sealed in a 3.00 L container at 476 oC. The equilibrium constant, Kc, is 2.50 (in M-1) for CO(g) + Cl2(g) = COCl2(g)
Calculate the equilibrium molar concentration of CO.
2) Chemists studied the formation of phosgene by sealing 1.08 atm of carbon monoxide and 1.22 atm of chlorine in a reactor at a certain temperature. The pressure dropped smoothly to 1.41 atm as the system reached equilbrium. Calculate Kp (in atm-1) for
CO(g) + Cl2(g) = COCl2(g)
