Variation of the dimensionless peak current$\sqrt{\pi }{\chi }_{\text{p}}$ with the dimensionless rate constant κ ₁ for the EC reaction mechanism. The dimensionless peak current $\sqrt{\pi }{\chi }_{\text{p}}$ is constant only for very small (log(κ₁) < −3) and very large (log(κ₁) > 4) values of the rate constant. In the former case, the limiting value of 0.4463 is approached; for an explanation of the black bar on the abscissa, see text, Section “EC mechanism — dependence on k₁”.
