## tested: gibbs free energy derivation?

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

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

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

### tested: gibbs free energy derivation?

Hi,

I understand that it's important to understand the derivations and how we find a quantitave relation between the Gibbs free energy and the maximum non expansion work that a system can do..

I remember that Professor Lavelle went over this in class but I don't remember him saying we were going to be tested on it, but in discussion a student said we would..

Was wondering if anyone remember him commenting on it or not..

I heard one of the TAs said we should know how to derive the formulas for reversible/irreversible expansion work earlier this quarter. I don't think we have to know the specifics about deriving $\Delta$G, but it would be helpful to know!
