15. 1/2 for the prewave potential region in Figure 2, inset B, has an intercept, which is not predicted by eq 8, that is thought to arise from lack of correction of the very small currents in the prewave potential region for the background currents which flow as a result of capacitative charging at the disk electrode alone. Applying a correction is complicated by the fact that the clusters tend to adsorb on the working electrode; such adsorption is in principle of no consequence for steady state currents, but it does mean that a correction derived from a naked electrode background current is strictly speaking inexact.
