The equilibrium constant, K, for the following reaction is 1.20E-2 at 500 K.PCl5(g) PCl3(g) + Cl2(g)An equilibrium mixture of the three gases in a 1.00 L flask at 500 K contains 0.279 M PCl5, 5.79E-2 M PCl3 and 5.79E-2 M Cl2. What will be the concentrations of the three gases once equilibrium has been reestablished, if 3.52E-2 mol of PCl3(g) is added to the flask?[PCl5] =?M[PCl3] = ?M[Cl2] = ?M
