COCl(2) gas decomposes as: COCl(2)(g) ...

`COCl_(2)` gas decomposes as:
`COCl_(2)(g) hArr CO(g)+Cl_(2)(g)`
If one mole of He gas is added in the vessel at equilibrium at constant pressure then

A

`[COCl_(2)]` increases.

B

"moles" of `CO` will increases.

C

The reaction goes in forward goes in forward direction.

D

`K_(c )=1`

Text Solution

Verified by Experts

The correct Answer is:
B, C
`COCl_(2)(g) hArr CO(g)+Cl_(2)(g), Deltan_(g)=2-1=1`
When an inert gas is added at constant `P`, the reaction shifts where `Deltan_(g) gt 0` (forward direction).
Hence, (b), (c ) are correct.
