## Gibbs free energy idea

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

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

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

### Gibbs free energy idea

What exactly is Gibbs free energy? (conceptually speaking)

I believe that in class Dr. Lavelle mentioned the change in Gibbs free energy is the energy free to do useful work.

Gibbs free energy is the energy of a system that is free to do work at constant temperature and pressure.
