## work and free energy

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

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

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

### work and free energy

what is the relationship between free energy and work?

Free energy is the amount of energy that is free to do non-expansion work so delta G = we,max

### Re: work and free energy

The change in free energy (delta G) for a spontaneous process is the energy that is available to do useful work. We were also given an equation in lecture, wmax = delta G, where maximum work is done by a process at constant temperature and pressure. Hope that helps!
