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.

Reaction Order Ambiguity in Integrated Rate Plots Joe Lee
This article provides a theoretical and statistical justification for the necessity of monitoring a reaction to a substantial fraction of completion if integrated rate plots plots are to yield unambiguous orders.

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.

Using CBL Technology and a Graphing Calculator To Teach the Kinetics of Consecutive First-Order Reactions José E. Cortés-Figueroa and Deborah A. Moore
This work proposes a demonstration to introduce first-order reactions using the CBL system. It then presents the analysis of two consecutive first-order reactions. The values of the rate constants that govern each reaction's rate are determined using the graphing and statistical capabilities of a TI-83 calculator.

Monitoring self-association of a hydrophobic peptide with high performance liquid chromatography: An undergraduate kinetic experiment using the antibiotic gramicidin A Braco, Lorenzo; Ba, M. Carmen; Abad, Concepcin
The authors propose a kinetic experiment that uses high performance liquid chromatography to determine the rate and equilibrium constants in a very simple manner, and separate the molecular species under study.

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.

The definition of the rate of a chemical reaction Canagaratna, S. G.
Most texts take it as obvious that the rate of a reaction may be defined in terms of changes in concentration; this definition is valid only if the reaction takes place without change of volume.

Passage of fruit flies through a hole. A model for a reversible chemical reaction Runquist, Elizabeth A.; Runquist, Olaf
The passage of fruit flies through a single orifice provides an excellent model for illustrating the principles of equilibrium and chemical dynamics; the results are found to be temperature dependent and reproducible.
