Problem

For the reaction:

PCl3 (g) + Cl3 (g) ⇌ PCl5 (g)           K c = 24.3

a system is prepared with

[PCl3] = 0.10 M; [Cl 2] = 0.15 M; [PCl 5] = 0.60 M.

Which response is correct? 

a. the reaction is at equilibrium and concentrations will not change

b. the amount of PCl 5 will increase

c. more PCl3 will form

d. the reaction will shift right

e. the amount of PCl 3 will increase while the concentration of Cl 2 will decrease.
