1 2D (a) 1 2(V) 1 C a A where V is the potential scan rate in V/s and Ca is analyte concentration in mol/cm3. Hence, reversible reactions may be diagnosed using the following criteria: • Peak separation ΔEp = Ep Red - E p Ox = 59 mV (59 ≅ 2.303 nF/RT at 298 K) • ip Ox/i p Red = 1 • ip Ox and i p Red ∝ V1/2 • Ep Ox and E p Red ...
