## Gibbs LS7A

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

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

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

### Gibbs LS7A

In LS7A, two equations are given for Gibbs free energy:

1) deltaG = deltaH - TdeltaS
2) deltaG = G(standard) + RTlnQ

Can someone relate these two equations? If deltaG is a state function (does not change with path), why would the concentrations of products and reactants affect deltaG?

For your second question: Changing the concentrations of products and reactants would change Q which is apart of the second equation

We aren't required to know the second equation for the midterm; this is covered in chapter 5, which Lavelle hasn't gone over yet
