Cyclic voltammetry was used to study the response of an aqueous 1.46 mM solution of Ferrocyanide, Fe(CN)64‐ at a 2.5 mm diameter electrode. KCl was present at a level of 1.0 M as supporting electrolyte. Four CVs were run at various scan rates producing a liner graph of peak current vs square root of scan rate with a gradient of 4.23×10-5. Calculate the diffusion coefficient of Ferrocyanide.

Fe(CN)64‐ ↔ Fe(CN)63‐ + 1e-
