Question

Following two equilibrium is simultaneously established in a container: $P C l_{5} (g) ⇌ P C l_{3} (g) + C l_{2} (g)$ and $C O (g) + C l_{2} (g) ⇌ C O C l_{2} (g)$
If some Ni(s) is introduced in the container forming $N i (C O)_{4}$ (g), then at new equilibrium:

P C l_{2}

Solution

The correct option is B $P C l_{3}$ concentration will decrease
Ni reacts with CO. Hence, the equilibrium for the reaction $C O (g) + C l_{2} (g) ⇌ C O C l_{2} (g)$ will shift to left so that more and more CO is formed. Due to this, the concentration of chlorine increases. Hence, the equilibrium for the reaction $P C l_{5} (g) ⇌ P C l_{3} (g) + C l_{2} (g)$ will shift to left so that more and more chlorine is consumed. Hence, the concentration of $P C l_{3}$ will decrease.
