WebThe change in free energy ( ΔG) is also a measure of the maximum amount of work that can be performed during a chemical process ( ΔG = wmax ). Consequently, there must be a relationship between the potential of an electrochemical cell and ΔG; this relationship is as follows: ΔG = − nFEcell During a reversible electrochemical reaction at constant temperature and pressure, the following equations involving the Gibbs free energy hold: • (see chemical equilibrium), • (for a system at chemical equilibrium), • (for a reversible electrochemical process at constant temperature and pressure), fritz wlan software
