✦ Synopsis

An analytical solution is presented for the case of double potential step chronoamperometry at a stationary planar electrode for the case of heterogeneous charge transfer control. Extension of the result to multiple potential steps gives the current-potential response for differential normal pulse voltammetry. The dependence of the response on the experimental parameters is examined. The dependence on duration of the first pulse is especially significant, for the case of long duration of the first pulse corresponds to the widelyused technique ofditkrential puke voltammetry. The advantage of using shorter durations for the first pulse (ie using differential norma pulse voltammetly) when examining irreversible reactions is shown.
