Data Pooling in a Chemical Kinetics Experiment: The Aquation of a Series of Cobalt(III) Complexes  Richard S. Herrick, Kenneth V. Mills, and Lisa P. Nestor
Describes an experiment that introduces students to integrated rate laws, the search for a mechanism that is consistent with chemical and kinetic data, and the concept of activation barriers and their measurement in a curriculum whose pedagogical philosophy makes the laboratory the center of learning for undergraduates in their first two years of instruction.

An Inexpensive Kinetic Study: The Reaction of FD&C Red #3 (Erythrosin B) with Hypochlorite  Maher M. Henary and Arlene A. Russell
Students use a desktop visible spectrophotometer to quantitatively follow the rate of disappearance of FD&C Red #3 with hypochlorite. The first-order reaction in both dye and bleach yields simple data that students can easily process and graph using spreadsheet software to obtain the rate constant and the rate law.

Textbook Deficiencies: Ambiguities in Chemical Kinetics Rates and Rate Constants  Keith T. Quisenberry and Joel Tellinghuisen
Recommends that textbook authors make it clear that (i) the reaction rate and rate constant cannot be defined unambiguously without explicitly stating the reaction for which they apply and therefore (ii) the relation between the half-life, which is a physical property of the reaction system, and the rate constant depends upon how the reaction is written.

An Analogy to Help Students Understand Reaction Orders  Charles J. Marzzacco
This article describes a simple analogy to help students understand the concept of the rate law for a chemical reaction. The analogy involves the mathematical relationships between various characteristics of a cube and the length of its edge.

Catalysis: New reaction pathways not just a lowering of the activation energy  Haim, Albert
The explanation that the increased rate associated with a catalyzed reaction is the result of a lowering of the activation energy cannot always be correct.

The study of a simple redox reaction as an experimental approach to chemical kinetics  Elias, Horst; Zipp, Arden P.
The authors present a kinetics experiment based on the oxidation of iodide ions that, like the iodine clock, is quick and easy to perform but has the advantage of being followed directly rather than indirectly.
