Extending Gibbs Free Energy

[laurence14b2f]

Hey everyone! How do we extend the concept of Gibbs free energy to non-equilibrium thermodynamics, particularly in systems far from equilibrium? Thanks!

In non-equilibrium thermodynamics, particularly for systems far from equilibrium, the direct application of ΔG becomes more complex because such systems may not be well-described by simple state functions like H and S, which are typically defined under conditions of equilibrium. In these cases, the concept of free energy needs to be adapted or extended. This often involves considering the rate of energy dissipation or the flow of energy through the system, and how far the system is from its equilibrium state.
