### Gibbs free energy and max work

Why is gibbs free energy equal to maximum work?

I think Gibbs free energy is the maximum work at constant temperature and pressure if the system is reversible and the work is non-expansion work form a closed system.

### Re: Gibbs free energy and max work

The Gibbs free energy is equal to the max amount of non-expansion work that comes from a closed system. When a system goes from its initial state to its final state, Gibbs free energy = (work exchanged by the system with its surroundings) - (work of the pressure force).
