## 9.73 part d: if delta S is greater than 0, why is the reaction spontaneous

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

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

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

### 9.73 part d: if delta S is greater than 0, why is the reaction spontaneous

If delta S of the reaction is positive, why will the reaction be spontaneous?

When looking at delta G = delta H - T delta S, since T is positive, if delta S is positive as well, as long as (T delta S) is greater than delta H, delta G would be negative and it's spontaneous. Also, things generally want to have greater entropy.
