## Standard form

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

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

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

### Standard form

When calculating gibbs free energy, do you take into account the stable form, which would made it equal to 0? Or is that only for enthalpy?

### Re: Standard form

For pure elements at standard state, the deltaG of formation will also be zero, just like the enthalpy
