    • If it is assumed that the rate of the interfacial ET reaction is determined by the collision frequency of the redox moiety with the monolayer surface and the probability of electron transfer per collision (at that surface, as discussed in ref 41 a, the predicted values of k°(/ T) would be very different because the rate of ET is then governed by the same physical processes that govern mass transport. However, such a rudimentary collisional model ignores the many demonstrations11,15 of distance-dependent, long-range interfacial ET.41a A more detailed comparison between the results of the theoretical approaches described here and the results of calculations based on collisional models is beyond the scope of the present paper
