## Maximum Work

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

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

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

### Maximum Work

Why is delta G equal to maximum work when T and P are constant?

I'm not sure how to mathematically prove it, but delta G is supposed to represent the maximum amount of work possible at constant pressure and temperature. Because G = H-TS = U+PV-TS.

It is a part of the laws of thermodynamics.
