This experiment is designed specifically for students with little knowledge of radical reactions and provides an introduction to the gas-phase chemistry of radicals. Experimental planning based on the student's own observation is an important component of the experiment. (Author/MA)

Describes an undergraduate biological chemistry laboratory experiment which provides students with an example of pseudo-first-order kinetics with the cardiac glycoside inhibition of mammalism sodium and potassium transport. (SL)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes an experimental procedure for illustrating general principles of photochemical reaction kinetics. (SL)

Describes an organic chemistry experiment for teaching the basic concepts of chemical kinetics. Provides background information about first- and second-order reactions, experimental procedures of the Diels-Alder reaction between cyclopentadiene and dimethyl fumarate, and the experimental results. (YP)

Provides an overview of an experiment on reaction kinetics of the anthracene-hydrogen system. Includes a description of the laboratory equipment, procedures, and data analysis requirements. Points out the advantages of the recommended technique. (ML)

Presents background information, procedure, and results of an experiment, using easily obtainable chemicals and equipment, illustrating chemical kinetics. The experiment may be done in a letter as one four-hour physical chemistry laboratory period. (JN)
