NEET levelSingle correct optionDifficulty 1 of 3ce119

Which relation correctly connects the standard Gibbs energy change and the equilibrium constant?

A $Δ G^{\circ} = RT ln K$
B $Δ G^{\circ} = - RT ln K$
C $Δ G^{\circ} = - R ln K / T$
D $Δ G^{\circ} = - K ln (RT)$

Answer: B

At equilibrium

Δ G = 0 = Δ G^{\circ} + RT ln K

, which gives

Δ G^{\circ} = - RT ln K

. A large

K

therefore corresponds to a negative

Δ G^{\circ}

.
