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?
