## Gibbs Free Energy and Spontaneity

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

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

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

### Gibbs Free Energy and Spontaneity

Could a reaction have a negative delta g and favor reactants or would it always favor the products?

If delta G is less than zero, this means a reaction is always product-favored
If delta G is greater than zero, this means a reaction is always reactant-favored

### Re: Gibbs Free Energy and Spontaneity

delta G is negative for any reaction where delta H is negative and delta S is positive. Any reaction for which delta G is negative should be spontaneous.
