The correct relationship between free energy change in a reaction and the corresponding equilibrium constant `K_(c)` is:

Options

A. `DeltaG^(@)=RT` In `K_(C)`
B. `-DeltaG^(@)=RT` In `K_(C)`
C. `DeltaG=RT` In `K_(C)`
D. `-DeltaG=RT` In `K_(C)`

Answer

D

Explanation

`DeltaG=DeltaG^(@)+RT` ln `Q` , where `Q` is reaction quotient, at equilibrium `DeltaG=)` and `Q=K_(c)`
` :. -DeltaG^(@)=RT` In `K_(c)`
