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.

Steel Wool and Oxygen: A Look at Kinetics  James Gordon and Katherine Chancey
An experimental method is described to study the kinetics of the reaction of the iron in steel wool with molecular oxygen. A calculator-based data collection system is used with an oxygen gas sensor to determine the order of the reaction with respect to oxygen. Using the graphical method, students determine that the reaction follows first-order kinetics with respect to oxygen.

Don't Be Tricked by Your Integrated Rate Plot: Reaction order Ambiguity  Sue Le Vent
Integrated rate equations (for constant reaction volume) may be given in terms of relative reactant concentration, C (= concentration/initial concentration) and relative time, T (= time/half-life); in these forms, the equations are independent of rate constants and initial concentrations.

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.

Kinetics in Thermodynamic Clothing: Fun with Cooling Curves: A First-Year Undergraduate Chemistry Experiment  Casadonte, Dominick J., Jr.
A series of experiments examining the phenomenon of cooling by producing part of the cooling curve for water at different initial temperatures, focussing on the fact that the curve is nonlinear (unlike the information presented in many texts).

A stabilized linear direct reading conductance apparatus. The solvolysis of t-butyl chloride  Cyr, T.; Prudhomme, J.; Zador, M.
A simple ac conductivity apparatus for experiments in chemical kinetics is described; the instrument is sufficiently reliable that it can be used by first year students and assembled in a few hours.
