## Equilibrium constant from G

$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

### Equilibrium constant from G

Where is the equation $\Delta G=-RTln(K)$ derived from?

### Re: Equilibrium constant from G

It comes from the equation $\Delta G = \Delta G^o +RTlnQ$
When the reaction is at equilibrium $\Delta G$ is equal to 0 and Q turns into K.
