8. The volume of a 1.00- L container consisting of 0.00400MPCl(g),0.100MPCl3(g), and 0.200MCl2(g) at equilibrium is doubled. The reaction is PCl5(g)PCl3(g)+Cl2(g). (a) Calculate Qc after the container changes in size, but before any shift occurs. (b) In which direction does the equilibrium shift? (c) What are the new equilibrium concentrations
