we are given with the equation 2POCl3 (g) + energy 2PCl3 (g) + O2 (g). In this case, to shift the equilibrium to the right, we increase the concnetration of the reactants or decrease the concentration of products from Le Chatelier's principle. The answer is A.) The equilibrium shifts to the right and the concentration of PCl3 (g) increases.
