Science Homework Help. The equilibrium constant, K, for the following reaction is 5.37E-2 at 540 K. PCl

The equilibrium constant, K, for the following reaction is 5.37E-2 at 540 K.

    PCl5(g) PCl3(g) + Cl2(g)


An equilibrium mixture of the three gases in a 18.5 L container at 540 K contains0.167 M PCl5,   9.48E-2 M PCl3 and 9.48E-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 9.64 L? 

    [PCl5] =  M
    [PCl3] =  M
    [Cl2] =  M

    It says you have to use the quadratic formula
