stability and spontaneity

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

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

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

stability and spontaneity

can someone please explain why it is more stable if delta G is negative/spontaneous?

Re: stability and spontaneity

If delta G is negative, that means Gibbs free energy is being released (so we are going from a higher energy state to a lower energy state, which is always optimal).
