## Intensive vs extensive

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

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

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

### Intensive vs extensive

Is gibbs free energy intensive or extensive?

### Re: Intensive vs extensive

I would assume that Gibbs free energy is an extensive property since the feasibility of a reaction depends on factors such as the amount of matter/availability of reactants, etc. Please correct me if I'm wrong!

Gibbs free energy is an extensive property. More matter in the system means the amount of maximum possible work available is also more.

It is extensive because its magnitude is dependent on the amount of a substance in a given thermodynamic state

Gibbs free energy is an extensive property. Intensive properties are independent of the size of a thermodynamic system.
