Generalized Numerical Method for Stationary Electrode Polarography. Application to Reactions Involving Second-Order Homogeneous Chemical Complications.

H2 Evolution at an Electrochemical “Underpotential” with an Iridium-Based Molecular Photoelectrocatalyst

“…CA analysis of second-order reactions cannot be solved quantitatively but can be estimated using working curves (See SI Section IV for details). 49 As will soon become clear, however, the rate law is complex and likely changes as a function of applied potential, so both firstand second-order treatments deviate from ideal behavior. Furthermore, neither electroanalytical treatment was developed for a reaction that involves a photochemical step.…”

“…Our more recent mechanistic study showed that the photochemical H 2 release reaction is bimolecular, so a second-order treatment of the data would be required if photochemical H 2 evolution is the rate-determining step. CA analysis of second-order reactions cannot be solved quantitatively but can be estimated using working curves (See SI Section IV for details) . As will soon become clear, however, the rate law is complex and likely changes as a function of applied potential, so both first- and second-order treatments deviate from ideal behavior.…”

Network simulation of the first‐ and second‐order catalytic mechanism for chronoamperometry

“…17). In this case, since an exact solution is not known as yet, we compared our results with those given the Crank-Nicolson modification of the finite difference [5] and the orthogonal collocation [6] methods. As it can be seen from Table 2 our results are in good agreement with theirs and no problems connected with second-order reactions arose.…”

Analysis of electrochemical mechanisms by finite difference simulation and simplex fitting of double potential step current, charge, and absorbance responses

“…Because the computation time at a given At is almost independent of the method, the smaller the absolute value of the slope, the more efficient the method. The integrated rate equation approach was used by Booman and Pence (22) although the system of differential equations being solved numerically was different from those considered here because nonlinear transformations had been applied. Flanagan and Marcoux (58) briefly mention the advantage of the integrated rate law and suggest that when integration is complicated a numerical technique such as Runge-Kutta be applied.…”
