What is Faraday constant?

Definition 9.1 University Chemistry — Year 2 · Chapter 9 — Thermodynamics of Electrochemical Cells

The Faraday constant is the electric charge of one mole of elementary charges, F=NAe=96 485.33 C/molF = N_A e = 96\,485.33\,\mathrm{C}/\mathrm{mol}.

A cell as a thermodynamic system at constant temperature and pressure: it exchanges heat with its surroundings and delivers electrical work through the external circuit. With the sign convention of the first law (work and heat received counted positive), W_ el = -nFU\,d.
