Question

At a certain temperature, Kc = 0.18 for the following reaction:
PCl3 (g) + Cl2 (g) PCl5 (g)
Suppose a reaction vessel at this temperature contained these three gases at the following concentrations:
[PCl3] = 0.420 M, [Cl2] = 0.240 M, [PCl5] = 0.00500 M:

(10a): Is the system in a state of equilibrium? Justify your answer with a calculation.
(10b): If the system is not in equilibrium, which direction will the reaction proceed to reach equilibrium?
