## thermodynamically stable

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

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

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

### thermodynamically stable

what does it mean to b thermodynamically stable? how does this relate to gibbs free energy?

i never saw this in our notes. will we be tested on this?

### Re: thermodynamically stable

Thermodynamically stable means that the reaction is spontaneous. Thus, when △G is negative, it is thermodynamically stable.

### Re: thermodynamically stable

If deltaGf < 0, the reaction is said to be favorable and thermodynamically stable.

### Re: thermodynamically stable

A reaction is thermodynamically stable when delta G (change in Gibbs free energy is less than 0). This usually means that delta H is negative and delta S is positive, but depending on the temperature of the reaction, it can be thermodynamically unstable or stable.

### Re: thermodynamically stable

A reaction is thermodynamically stable if it's spontaneous (aka when deltaG<0)

### Re: thermodynamically stable

Thermodynamically stable is equivalent to a negative value for Gibbs. This also means that the rxn is favorable.
