## applying gibbs free energy

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

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

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

### applying gibbs free energy

What exactly does Gibbs free energy tell us about an equation? How is it applied?

Gibbs free energy tells us if a reaction is spontaneous or not.

Gibbs free energy also represents the maximum work from the energy that is released.

Gibbs free energy tells us about the spontaneity of a reaction. If it is less than 0, then the process is exergonic and will proceed spontaneously in the forward direction. If it is greater than 0, then the process is endergonic and will proceed spontaneously in the reverse direction. If it is equal to 0, then the process is at equilibrium.

Which equation you use can tell you different things about Gibbs free energy. Look at the different variables in each equation and use what is applicable based on the question.

Gibbs free energy allows us to determine if an equation is spontaneous or not.
