## 9.65 6th edition

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

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

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

### 9.65 6th edition

When you balance the equations for 9.65 in the 6th edition, why are the balanced coefficients in fractions?

The coefficients are fractions because you trying to balance the reactants such that you would only get 1 mole of product. The questions does not state how many moles, but you can assume 1 mole since you are solving for standard entropy of formation
