The microwave-mediated preparation of lophine (2,4,5-triphenylimidazole) is described. This experiment allows for an introduction to the emerging technology of microwave-assisted organic synthesis while providing an opportunity for students to employ the principles of carbonyl chemistry in devising a mechanism to explain the formation of the…

Describes an undergraduate organic chemistry laboratory experiment which utilizes the solvolysis of organic halides to demonstrate first and second order reaction kinetics. The experiment also investigates the effect of a change of solvent polarity on reaction rate, common-ion and noncommon-ion salt effects, and the activation parameters of a…

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)

A reaction kinetics experiment for the chemical engineering undergraduate laboratory course was developed in which in-situ Fourier Transfer Infrared spectroscopy was used to measure reactant and product concentrations. The kinetics of the hydrolysis of acetic anhydride was determined by experiments carried out in a batch reactor. The results…

Explains a series of experiments that increased students' awareness and understanding of activation energy, reaction transition states, rates of reaction, provided a neat example of the diagnostic utility of infrared spectroscopy and furnished insight into the accidental research situation. (Author/GS)

Thirteen experiments and 15 activities are presented in this unit handbook for student use. The experiment sections are concerned with naked-eye observation in astronomy, regularity and time, variations in data, uniform motion, gravitational acceleration, Galileo's experiments, Netson's laws, inertial and gravitational mass, trajectories, and…

This laboratory manual, part of a series of instruction books on basic experimental chemistry, is designed to provide the secondary school students of developing countries in Asia with laboratory experiences that bring out the fundamental concepts and ideas of chemical kinetics. Taking into consideration the possibility of limited facilities of…

Describes a laboratory experiment, suitable for senior undergraduates, that illustrates energy transfer processes in photochemical reactions. (MLH)

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

Describes some of the general principles involved in the planning of a teaching sequence. Discusses in more detail one example of a complete syllabus including major concepts and experiments. (Author/TS)

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Describes an organic chemistry experiment for teaching the basic concepts of chemical kinetics.
