The table below includes current–potential data for a reversible cathodic steady-state wave with the limiting diffusion current 25 mA. (a) Using these data, plot the logarithm term in Equation (13.24) as a function of potential. (b) Use the plotted straight line to determine the half-wave potential and the number of electrons in the electrochemical reaction. (c) Assuming that the potential was measured with respect to the saturated calomel electrode (SCE), calculate the half-wave potential with respect to the standard hydrogen electrode (SHE). ESCE = +0.244 V vs. SHE. This exercise demonstrates the logarithmic analysis of a steady-state voltammetric wave
