Now if we convert all of this to a free energy, the standard free energy for the NADH oxidation/UQ reduction is -nFE 0 or -(2)(96.5 kJ/mole V) ... WitrynaThat’s why both the pyruvate/lactate and NAD+/NADH half-cells above have negative reduction potentials even though we wrote the first as a reduction and the second as a oxidation. The reduction potential is a relative value - in order to know whether the pyruvate/lactate half-reaction will be favorable, we need to know where electrons …
