## Work and Gibbs 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 Gibbs Free Energy

When will work be equal to Gibbs free energy? (Which variables need to be constant for this phenomenon to happen?)

Delta G equals the maximum amount of work done at constant pressure and temperature.

I'm not sure if this is what you were asking but I hope it helps.

i think temperature and pressure have to be constant, so that no energy is released as heat or entropy, but all used as work

I think it has to be when entropy is 0, and q = -w. So, there is no change in internal energy and no change in entropy.
