## free work

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

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

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

### free work

why is -G making the reaction spontaneous?

Gibbs free energy calculates the maximum amount of work that can be done. If G is negative it means work is being done, not work is needed to be done, and in a spontaneous reaction work is done, not needed.

-G means that work is being done by itself, so it is spontaneous, and +G means that work is needed, so it is not spontaneous
