At a certain temperature, an equilibrium mixture in a 1.00L container consists of 0.00400MPCl5(g),0.100 MPCl3(g), and 0.200MCl2 (g). (a) Calculate KC for PCl5(g)PCl3(g)+Cl2(g); (b) To this mixture is added 0.100mol of PCl3(g). Predict whether the new equilibrium concentrations will be higher than, lower than, or equal to the original equilibrium concentrations after the reaction returns to equilibrium; (c) Calculate the new equilibrium concentrations of the three gases. Are your answers consistent with your predictions
