Homework Help: Chem 2

Posted by Anonymous!! on Monday, March 31, 2014 at 1:20pm.

Phosphorus pentachloride decomposes according to the chemical equation
PCl5<-->PCl3 +Cl2
A 0.260 mol sample of PCl5(g) is injected into an empty 2.75 L reaction vessel held at 250 C. Calculate the concentrations of PCl5(g) and PCl3(g) at equilibrium.

Please help I'm not sure where to go after you solved for x (Using the quadratic formula)

I got x=0.0921

is this correct? and how do i get the PCl5 and PCl3 from that?
