The equilibrium constant `(K_(p))` at `27^(@)C` for a homegenous gasesous reaction is `10^(-8)`. The standard free energy change `DeltaG^(@)` for the reaction is: (Use `R=2 cal K^(-1)mol^(-1)`)

A

`11.05 kcal`

B

`-1.8 kcal`

C

`-4.1454 kcal`

D

`+4.1454 kcal`

Text Solution

Verified by Experts

`-DeltaG^(@)=2.303RTlogK_(p)`
`=2.303xx2xx300xxlog10^(-8)`
`:. DeltaG^(@)=11054.4 cal=11.05kcal`
