Dependence of the maximal Hill coefficient (Inline graphic) and the activation voltage at this slope (Vmax) on c. The graph for Inline graphic was plotted based on Eq. 12 (shaded, left y-axis) and that of Vmax (black, right y-axis) according to the equation Vmax = (RT/2ZF)ln(1/(KOKC)), derived by solving the equation ∂nH(V)/∂V = 0, which is a normalized second derivative of the MWC open probability expression. In this plot, for convenience, KC was assigned a value of 1, whereas KO values range from 10−5 to 105. See text for further discussion.
