## 9.61

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

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

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

### 9.61

So if the the rxn that we are trying to find the delta G for has two products o we just add their enthalpies and entropies together and then solve for delta G?

### Re: 9.61

I would find the delta G for each product using their enthalpy and entropy values and then add the delta G for all the products. I would then do the same for the delta G of all reactants and then do sum of delta G products - sum of delta G reactants to find the delta G for the reaction. Hope this helps!
