The correct equation of equilibrium constant in terms of Gibbs energy is
View answer and explanation
Correct option: A
K=eāˆ’Ī”G∘/RTK=e^{-\Delta G^{\circ} / R T}
Option A (K=eāˆ’Ī”G∘/RTK=e^{-\Delta G^{\circ} / R T}) is correct because it represents the correct relationship between the equilibrium constant (K) and the standard Gibbs free energy change (Ī” G°).
