## Gibbs Free and Direction of Reaction

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

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

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

### Gibbs Free and Direction of Reaction

If Gibbs is positive and spontaneous, why does it mean that it will produce more reactants?

### Re: Gibbs Free and Direction of Reaction

that's a good question haha! i've just always remembered that negative delta g means the reverse reaction is spontaneous and the reactants are favored, but i've never really thought about it before. i hope someone can answer! :)

When Gibbs Free Energy is negative, it is spontaneous. When it's positive, it will produce more reactants, because it will not occur as easily as it would with spontaneous reactions.

When delta G(naught) is positive then more reactants are present than products at equilibrium and vice versa when it is negative.
