Predict and calculate the effect of concentration changes on an equilibrium system. Some PCI5 is allowed to dissociate into PCI3 and Cl₂ at 523 K. At equilibrium, [PC] = 0.143 M, and [PCI3] [Cl₂] = = 8.45x10-2 M. Additional PCI5 is added so that [PCI5]new = 0.235 M and the system is allowed to once again reach equilibrium. PCI5(g) =PC13(g) + Cl₂(g) K = 5.01x10-2 at 523 K = (a) In which direction will the reaction proceed to reach equilibrium? (b) What are the new concentrations of reactants and products after the system reaches equilibrium? [PCI5] = [PCI 3] = [Cl₂] M M M
