Phosphorus pentachloride decomposes according to the


Phosphorus pentachloride decomposes according to the chemical equation

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

Kc = 1.80 at 250 degrees C

A 0.361 mol sample of PCl5(g) is injected into an empty 4.80 L reaction vessel held at 250 °C. Calculate the concentrations of PCl5(g) and PCl3(g) at equilibrium.

Calculate the concentrations of PCl5 (g) and PCl3 at equilibrium.

The answer for PCl 5 is .0035M

So all I need help with is the PCl3
