Making use of our automated setup, it is also possible to carry out a systematic variation of pH in our experiment to compare the reaction kinetics vs. OH -concentration to better understand the pH dependance of TEMPO catalysis. Figure shows the log-log plot of the observed rate constants of isopropanol electrooxidation as a function of the OH -concentration, calculated from CVs performed at 50 mV/s. The slope of this log-log plot gives us a reaction order of 1.3 with respect to OH -. We might expect the reaction to be first-order with respect to OH -due to a pre-equilibrium approximation of the deprotonation of the alcohol prior to rate-limiting step in Scheme 1, but the complex nature of reactions occurring near an electrode surface may cause deviations from such approximations. Regardless, the average reaction order of OH -across all substrates was calculated to be 0.9 ± 0.2, using the slopes of the linear fits with the highest R 2 for each substrate as the reaction order (Figure ). The ability to carry out informationally-rich kinetic analyses in an unsupervised fashion, like that shown in Figure , and to determine important kinetic parameters such as TOF and reaction orders demonstrates the capabilities of our automated platform for mechanistic analysis.
