## Outline of Thermodynamics

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

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

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

### Outline of Thermodynamics

What is the relationship between free energy and work?

Free energy is equal to the amount of energy that is available to do work. I think this means that the value of delta G is the maximum amount of work that a system can do.

Gibbs free energy, ΔG, is the maximum amount of energy from a system that can be used to perform useful work, in other words, work not associated with the expansion of a system.

### Re: Outline of Thermodynamics

The total amount of work a system can do is determine by the change in its free energy, or ∆G. When free energy decrease, or when ∆G is negative, the reaction is spontaneous and work is done during the process.
