![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, [PCI5] = 0.143 M, and [PCI3]
= [Cl₂] = 8.45×10-² M. Additional PCI5 is added so that [PC15] 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
