Problem

At a certain temperature, 0.0740 mol of PCl 5(g) were introduced into a one-liter container.

PCl5(g) ⇋ PCl3(g) + Cl2(g)

At equilibrium the concentration of PCl 3(g) was 0.0500 mol/L.

a) What were the equilibrium concentrations of Cl 2(g) and PCl5(g)?

 

 

 

b) What is the value of Kc at the temperature of the experiment?
