## w max

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

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

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

### w max

Can someone explain to me what w(max) is and why they will equal change of G at constant T and P

I'm not entirely sure, but how I understand it is that with constant temperature and pressure, the energy change is equivalent to the work done, assuming no heat is released. This would be w(max), or the maximum amount of work possible.

W(max) is the maximum amount of work possible. It appears that by definition G is the maximum non-expansion work that can be done under constant T and P.
