## Difference between calculations

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

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

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

### Difference between calculations

What is the difference between calculating delta G through G(products) - G(reactants) using values given and calculating delta G through the equation deltaG = deltaH - TdeltaS?

I don't think there is one. It mainly depends on the numbers you have available to you.
