7. s, is a measure of the reversibility of the electron-transfer reaction. The value given for 4 is approximate because no attempt was made to account accurately for the effects of solution resistance. The potentials are actually the half-wave potentials which differ from the reversible formal potential by a small term (usually less than 10 mV), involving the diffusion coefficients of reactant and product. The potentials have been referred to the reversible half-wave potential of the ferrocenium/ferrocene couple measured under the same conditions as used for 3-5.
