Following two eqilibrium is simultaneously establised in a container `PCl_(s(g)) hArr PCl_((3)(g)) + Cl_((2)(g)), CO_((g)) + Cl_(2(g)) hArr COCl_((2)(g))`. If some `Ni_((g))` is introduced in the container forming `Ni(CO)_(4)` then at new equilibrium

A

`PCI_3`. concentration will increase

B

`PCl_3` concentration will decrease

C

`CI_2` concentration will remain same

D

`CO` concentration will remain same

Text Solution

Verified by Experts

The correct Answer is:
B
CO is removed through complex formation `:. Cl_(2)` is formed through 2nd reaction `:. 1^(st)` reaction shifts in the backward direction
