Like other chemical reactions, redox reactions involve a free energy change. Reactions that move the system from a higher to a lower energy state are spontaneous and release energy, while those that do the opposite require an input of energy. In redox reactions, energy is released when an electron loses potential energy as a result of the transfer.A positive free energy change means energy must be put into a reaction to drive it forward. In fact, reduction potential and free energy are closely linked by the following expression: ΔG = −nFE0 Δ G = − n F E 0. in which n = number of electrons transferred in the reaction; F = Faraday's constant, 96 500 Coulombs/mol. …
