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.

A Student Laboratory Experiment Based on the Vitamin C Clock Reaction  Ed Vitz
Describes an adaptation of the vitamin C clock reaction to a student laboratory experiment in which the orders with respect to peroxide and iodide, the rate constant, and the activation energy are determined by the method of initial rates.

Let Us Give Lewis Acid–Base Theory the Priority It Deserves  Alan A. Shaffer
The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

The Blue Bottle Reaction as a General Chemistry Experiment on Reaction Mechanisms  Steven C. Engerer and A. Gilbert Cook
Using the scientific method (observe, question, hypothesize, experiment, repeat) students propose and test possible reaction mechanisms for the methylene blue-catalyzed oxidation of dextrose with its dramatic color change. Students are led to discover the three-step mechanism through a series of questions.

Synthesis of Aspirin: A General Chemistry Experiment  John A. Olmsted III
An experiment is described that is suitable for the early portion of the laboratory in a general chemistry course and integrates organic examples. It is the two-step synthesis of aspirin starting from oil of wintergreen. The mechanism for this synthesis provides examples of three major classes of chemical reactions: hydrolysis, condensation, and proton transfer.
