## 9.53

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

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

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

### 9.53

I understand how we need to use deltaG = deltaH - TdeltaS for this question, and how we need to use the tables in the textbook to find the values for deltaH and deltaS, however, why is the value of delta S listed in the solutions "97.6J/K/mol" ?
Where does that value come from?

Hi, Andrea,
This is deltaS of vaporization of ammonia that can be found in Table 9.1
