    Hey, I just got this problem wrong too a little while ago, but now understand the solution.

    It's an ICE setup:

    Initial:
    PCl5: 4.750 M
    PCl3: 0 M
    Cl2: 0 M

    Change:
    PCl5: -1.896 M
    PCl3: +1.896 M
    Cl2: +1.896 M

    Equilibrium:
    PCl5: 4.750 - 1.896 = 2.854 M
    PCl3: 1.896 M
    Cl2: 1.896 M

    PCl5 <---> PCl3 + Cl2

    Kc = [PCl3][Cl2] / [PCl5]
    Kc = (1.896)(1.896) / 2.854
    Kc = (1.896)^2 / 2.854
