The driving force DeltaG diminishes to zero on the way to equilibrium, just as in any other spontaneous process. Both DeltaG and the corresponding cell potential (E = (DeltaG)/(nF)) zero when the redox reaction comes to equilibrium. The Nernst equation for the redox process of the cell may be given as : E= E^(@) -(0.059)/( n) log Q The key to the relationship is the standard cell potential E^(@) , derived from the standard free energy change as : E^(@)=-(DeltaG^(@))/(nF) .
