## gibbs free energy -RTlnk

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

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

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

### gibbs free energy -RTlnk

under which conditions do you use the equation: deltaG=-RTlnk?

That equation is used when the system is at equilibrium.

I think this equation is used for the system at equilibrium, which is why K (equilibrium constant) is in there!
