An explicit finite difference program was used to generate double potential step chronoamperometric, chronocoulometric, and chronoabsorptometric response ratios for 22 two-parameter electrochemical mechanisms, 252 points per mechanism adequately covering a broad range of kinetic values. The distribution of errors in the data set is discussed, along with some theoretical aspects of digital simulation. Computer analysis of double step experiments using the data set and a simplex algorithm is described. The ability of double step methods to differentiate between mechanisms and the probable errors in kinetic parameters obtained by fitting typical data to working curves were demonstrated using the package.
