## Gibbs Free Energy

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

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

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

### Gibbs Free Energy

What is the difference between Gibbs free energy of formation and Gibbs free energy of reaction conceptually? Does the way in which they are calculated differ?

gibbs free energy of formation is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state.

### Re: Gibbs Free Energy

Gibbs free energy of reaction is the standard free energy of formation of products minus the standard free energy of formation of the reactants.
It is modeled by the equation: ΔG(rxn)=∑ΔG(products)−∑ΔG(reactants).
The standard free energies of formation can be used to calculate the free energy change of any reaction under standard conditions.
