The equilibrium constant for this problem is Kp = [cl2] [pcl3]/[Pcl5]. Kp equal to 2.24 x 10-2 is given, while the initial concentration of pcl5 is 0.235 M and that of pcl3 is 0.174 M. The equation now becomes 2.24x10-2 = (0.174+x) x / (0.235-x) where x is the concentration produced from rxn and that of cl2. The equilib concentration of cl2 is then 0.22 M.
