In which of the following equilibrium system the rate of the backward reaction is favoured by increase of pressure

A

`PC1_(5)hArrPC1_(3) + C1_(2)`

B

`2SO_(2) + O_(2)hArr2SO_(3)`

C

`N_(2) + 3H_(2)hArr2NH_(3)`

D

`N_(2) + O_(2)hArr2NO`

Text Solution

Verified by Experts

The correct Answer is:
A
The rate of backward reaction is favoured by increase of pressure in the reaction as `Delta n` is positive
`PC1_(5)hArrPC1_(3) + C1_(2)`
