Gibbs energy

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

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

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

Gibbs energy

What's the difference between delta G and then deltaG^0?

Re: Gibbs energy

Delta G^o is the standard free energy change based on standard state formation of 1 mol of the substance. Delta G is the free energy change of the substance not in the standard state.

Re: Gibbs energy

Delta G^0 is for standard conditions such as standard temperature (25 degrees celcius/298K). Delta G is for nonstandard conditions and depends on those, this means temperature, for instance, is not standard.
