Figure 6.3 Dependence of the apparent rate constants, determined by fitting the experimental
transients with (6.5), on the step fraction. The final potentials are 0.73 V (triangles), 0.755 V
(diamonds), 0.78 V (squares), and 0.805 V (circles). The value of the step fraction for
Pt(111) was estimated using a procedure described in [Lebedeva et al., 2002c]. The inset
shows the independence of the apparent “intrinsic” rate constant per step.
Figure 6.4 Dependence of the apparent rate constants and the apparent intrinsic rate constant
on the potential (“Tafel plots”), determined by fitting the experimental transients with (6.5).
