Explanation / Answer

consider the given equilibrium

PCl3 + Cl2 <---> PCl5

now

according to Lechatlier principle

upon bringin a change, the equilibrium will shift in a direction to counter the change

a) addition of PCl3

the equilibrium will try to reduce PCl3

so it will shift to right

b) removal of PCl3

the equilibrium will try to increase PCl3

so it will shift to left

c) removal of PCl5

the equilibrium will try to increase PCl5

so it will shift to right

d) removal of Cl2

the equilibrium will try to increase Cl2

so it wil shift to the left

so

the answers

a) shift to right

b) shift to left

c) shift to right

d) shift to left
