## Pressure & K

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

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

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

### Pressure & K

Why does reaction free energy depend on pressure and K?

### Re: Pressure & K

K will help tell us if the reaction is spontaneous, nonspontaneous, or at equilibrium, depending on its value. If you increase the partial pressure of the product, deltaG becomes more positive, and if you increase the partial pressure of the reactant, deltaG becomes more negative.
