## Homework question 9.55

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

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

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

### Homework question 9.55

Does anyone know why the solutions manual assumes the temperature is 298K (roomtemp) for the Gibbs Free Energy calculations even if we are not specifically told in the problem?

The default temperature when dealing with standard energy is usually 25 degrees Celsius unless otherwise noted.
