The following two equilibria exist simultaneously a closed vessel
`PCl_(5)hArrPCl_(3)(g)+Cl_(2)(g)`
`COCl_(2)(g)hArrCo(g)+Cl_(2)(g)`
If some CO is added into the vessel, t hen after the equlibrium is attained again, concentration of

A

`PCl_(5)` increases

B

`PCl_(5)` remains unchanged

C

`PCl_(5)`decreases

D

`Cl_(2)` increase

Text Solution

Verified by Experts

The correct Answer is:
C
`Cl_(2)` is present simultaneously in two equilibria. Decrease in its concentration shift both equilibria forward.
