What is the relationship between free energy and work?

If delta G is negative, then that means that free energy is released. That released energy can be used to do work.

when energy is released, that energy can be used to do work. So if the reaction has a -delta G you know that energy is being released.

Gibbs' free energy corresponds to the amount of work that can be performed in a given system. A positive delta G means that the system is not spontaneous, and a negative delta G means that the system is spontaneous.

If Gibbs free energy, or delta G, is negative, then it releases free energy, which can then be put towards doing work. This is why we have the relationship delta G = -w(max).

Delta G represents the maximum work that can be done by a voltaic cell. This is why it is possible to equate the two equations w(max)=-nFE(max) and deltaG(cell)=-nFE(cell).
