## Nonexpansion Work

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

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

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

### Nonexpansion Work

In the textbook, it states that Gibbs Free Energy tells us how much nonexpansion work we can get from the system. What does it mean by nonexpansion work?

In summary, "Expansion work is pressure-volume work, and nonexpansion work is anything else (electrical, friction, motional, etc.)."

### Re: Nonexpansion Work

As you said, Gibbs Free Energy is the maximum amount of non-expansion work that can occur in a closed system.non-expansion work is work not involving pressure and volume, as the person above stated: electrical work.
