## 9.55

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

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

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

### 9.55

It asks to write balanced equations before calculating enthalpy, entropy, and gibbs free energy. Does the equation need to have the smallest possible molar ratios? I balanced the equation as 3H2 (g) + N2 (g) --> 2NH3 (g) and I got a different answer for entropy than the solutions manual

They might convert the answer to per mole based
