Calculating Kc Equilibrium for PCl3 + Cl2 = PCL5 at 230°C

[kittymaniac84]

The equilibrium constant Kc for the reaction, PCl3 (g) + Cl2 (g) = PCL5 (g),
equals 49 at 230°C. If 0.400 mol each of phosphorus trichloride and chlorine are
added to a 4.0 Liter reaction vessel, what is the equilibrium composition of the
mixture at 230°C?
