The equilibrium constant, K, for the following reaction is 1.54×10-2 at 506 K:
PCl5(g) PCl3(g) + Cl2(g)
An equilibrium mixture of the three gases in a 15.7 L container at 506 K contains 0.207 M PCl5, 5.64×10-2 M PCl3 and 5.64×10-2 M Cl2. What will be the concentrations of the three gases once equilibrium has been reestablished, if the equilibrium mixture is compressed at constant temperature to a volume of 6.47 L?
