Question

For the reaction : CL2(g)+3F2(g)PCL3(g)+CL2(g)
(A) Introducing an inert gas at constant volume
(B) Introducing inert gas at constant pressure
(C) Introducing Cl2(g) at constant volume
(D) Increasing the volume of the container.​

Answer 1

Answer:

The equilibrium reaction is PCl

5

(g)⇌PCl

3

(g)+Cl

2

(g). When some PCl

5

is added its concentration is increased.

The equilibrium will shift to right so that more PCl

5

is consumed which will nullify the effect of increased concentration of PCl

5

. Due to this the equilibrium concentration of chlorine gas increases.
