The equilibrium constant, K, for the following reaction is 3.16×10-2 at 525 K.

PCl5(g) <----->PCl3(g) + Cl2(g)


An equilibrium mixture of the three gases in a 4.56 L container at 525 K contains 0.243 M PCl5,   8.77×10-2 M PCl3 and 8.77×10-2 M Cl2. What will be the concentrations of the three gases once equilibrium has been reestablished, if the volume of the container is increased to 10.3 L?

[PCl5] = M
[PCl3] = M
