## state functions

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

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

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

### state functions

Because all of the function in deltaG= deltaH -TdeltaS are state functions, does that mean that free energy is a state function as well?

Yes, Professor Lavelle told us in class that Gibbs Free Energy is also a state function.

Yes, I agree. Free energy is a state function because it does not depend on the path taken by the system to go from reactants to products. Refer to Lecture 9.

Yeah you're right free energy is a state function
