Introduction to Electron Transfer: Theoretical Foundations and Pedagogical Examples
Peer reviewed Peer reviewed
Direct linkDirect link
Piechota, Eric J.; Meyer, Gerald J. – Journal of Chemical Education, 2019
A central theme in introductory and advanced chemical education courses pertains directly to the transfer of electrons between atoms, ions, or molecules. This article presents theoretical treatments of electron transfer with specific attention toward applying these principles to experiment. The goal is to revitalize teaching electron transfer at…

Linear or Nonlinear Least-Squares Analysis of Kinetic Data?
Peer reviewed Peer reviewed
Direct linkDirect link
Perrin, Charles L. – Journal of Chemical Education, 2017
The disadvantages of the usual linear least-squares analysis of first- and second-order kinetic data are described, and nonlinear least-squares fitting is recommended as an alternative.

Some Considerations on the Fundamentals of Chemical Kinetics: Steady State, Quasi-Equilibrium, and Transition State Theory
Peer reviewed Peer reviewed
Direct linkDirect link
Perez-Benito, Joaquin F. – Journal of Chemical Education, 2017
The elementary reaction sequence A ? I ? Products is the simplest mechanism for which the steady-state and quasi-equilibrium kinetic approximations can be applied. The exact integrated solutions for this chemical system allow inferring the conditions that must fulfill the rate constants for the different approximations to hold. A graphical…
