how is work related to free energy or cell potentials?

Gibbs free energy is equal to the maximum non expansion work a reaction can do at constant pressure and temperature

the deltaG for a cell is the amount of useful work obtainable from a system at constant T and P.

thanks for your answer! how is work related to cell potential though?

### Re: work

To add on, the amount of work a system can do is determined by the total change in free energy. This relates to cell potential because in an electrochemical cell, the system converts chemical energy to electrical energy based on the system's cell potential. The about of work and free energy change depends on the cell potential and the number of electrons transferred.

### Re: work

The amount of work possible is dependent on the cell potential of the electrochemical cell

### Re: work

dG = max work possible ! This is because ideally, all energy released in the reaction would be used to do work. This is not realistic in nature however, because energy dissipates, etc.
