Gibbs free energy

Postby Marc Farah 3D » Mon Feb 13, 2017 2:10 pm

Why is it so that the work maximum is equal to delta G?

I think it's because delta G for a spontaneous process represents the energy that is free to do useful work(at constant temperature and pressure), or in other words Gibb's free energy, when negative, represents the total energy available that can do work on the system. However, if delta G is positive, it's not spontaneous, and therefore no work is being done

Gibbs free energy is the amount of energy available to do work, so the delta G of a redox reaction is the maximum amount of work that can be done by the reaction.
