Diffusion coefficient is an important mass transport related parameter governing an electrode reaction. It may be determined using transient voltammetry. An oxidation peak current of 2.08 × 105 A was obtained from a voltammetric experiment undertaken at 25 °C in an aqueous electrolyte medium containing 2.0 mM Red and 0.1 M KCl using a 3.0 mm diameter electrode at a scan rate of 100 mV s1. Calculate the diffusion coefficient (D) for Red using the Randles-Sevčik equation (unit cm2 s1). Use scientific notation, eg. 1E-3 = 0.001
