For the reaction taking place at certain temperature `NH_(2)COONH_(4)(s)hArr2NH_(3)(g)+CO_(2)(g)` if equilibrium pressure is 3 X bar then `Delta_(r)G^(@)` would be

A

`-"RT ln 9"-"3RT ln X"`

B

RT ln 4 `-3RT` ln X

C

`-3RT` ln X

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaG^(@)=-RTlnK_(p),K_(p)=(2x)^(2)X=4X^(3)`
`DeltaG^(@)=-RTln(4X^(3))`
`DeltaG^(@)=-RTln4-3RTlnX`
