96485Jmol
96485Jmol is an energy unit equivalent to one mol of Faraday's constant expressed in joules per mole rather than coulombs per mole. The numeric value 96485 originates from the elementary charge (1.602176634×10^-19 C) multiplied by Avogadro's number (6.02214076×10^23 mol^-1). When the charge is applied to an electric potential of one volt, the work done is equal to the electrical energy expressed in joules; thus 96485 J/mol equals 96485 C/mol at a potential of 1 V. This conversion is frequently used in electrochemistry, particularly in the calculation of Gibbs free energy changes and cell potentials for reactions involving one mole of electrons.
The unit is linked to the Nernst equation, which relates cell potential to standard potential, temperature,
In practice, 96485Jmol is used when calculating the change in free energy (ΔG) for electrochemical processes:
The unit maintains dimensional homogeneity with other thermodynamic quantities. While not declared in any international code
