## Gibbs Free Energy

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

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

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

### Re: Gibbs Free Energy

Gibbs free energy of formation is 0 for elements in their standard states.

It is equal to zero when neither the forward or the reverse reaction is favoured. The reaction proceeds until equilibrium is reached.
