Fig. 7: CV-evaluation by triangular Born-Fajans-Haber-Cycles.

Measured half-wave potentials of [Fc]⁺ and [NO]⁺ versus Ag⁺(10 mm)/Ag and [NO]⁺ versus [Fc]⁺/Fc in exemplarily selected 5FB and DCE = 1,2-Cl₂C₂H₄ solution at a scan rate of 100 mV s⁻¹. Knowing two out of the three values of the measurements, the third can be calculated in a Born-Fajans-Haber-Cycle approach. Hence, |ΔE| and |ΔG| errors can be calculated by using the relation ΔG = −zFΔE, with z = number of electrons, ΔE = potential difference, F = Faraday constant = 96,485 C mol⁻¹.⁶⁸ The mean errors of the calculated potential difference (ΔE) / the corresponding Gibbs energy difference (ΔG) are given in red in the center of the triangle. Note, E_1/2 potentials were rounded to two decimal places and rounding errors can occur.
