Figure 1.

Simulated voltammetric response of a two-electron transfer as a function of the difference between the formal potentials for the two processes. Ef1−Ef2: +50 mV (magenta), 0 mV (blue), and −50 mV (red). The black line represents the hypothetical limiting case in which the two electrons are transferred simultaneously. Simulations performed using DigiSim; other simulation parameters: v=100 mV s−1, D=10−5 cm2 s−1, r0=1 mm.
