in factors of 10. Eh, called the redox potential, is measured in volts. F is the Faraday constant, which is the electric charge of one mole of electrons (96,500 coulombs). F has a value of 0.059 V at 2 C. With these equations, you can express the energy available from a reaction either in terms of G, Eh or pE.
