The equilibrium constant, Kc, in 400K for the reaction PCl5(g) <----->PCl3(g) +Cl2(g) is 1.1*10-2

a. 1.0gr of PCl5 was initially placed in the reaction chamber with the volume of 250 ml.  

determine the molar concentrations in the mixture at equilibrium.

b. what percentage of PCl5 decomposed in 400K?

show detailed calculations in process, especially in solving for x equations in order to find concentrations at equilibrium. (quadratic equation)
