Describes an undergraduate physical chemistry experiment in which a low cost spectrofluorimeter is used to carry out elementary emission measurements on a transition metal complex. The students measure uncorrected emission and excitation spectra, and determine the rate constant for an exceedingly fast bimolecular reaction, the deactivation of an…

Five brief items are discussed. They include (1) preservation of reactive ions in solid solution, (2) the molecular partition function, (3) purification of methoxychlor, (4) a kinetics experiment, and (5) determining molecular weights of acids. (RWH)

Describes an experiment in which the rate of reaction can be followed using a colorimeter and data can be used to determine order of reaction, rate constant, and energy of activation. (GS)

Describes an interesting, inexpensive, and highly motivating experiment to study uniform and accelerated motion by measuring the position of a car as it crashes into a rigid wall. Data are obtained from a sequence of pictures made by a high speed camera. (Author/SLH)

Describes a heat transfer experiment that demonstrates kinetic behavior using measurements of the rates of cooling and warming of liquids. (MLH)

Describes an undergraduate physical chemistry experiment in which the kinetics of the various reactions involved in the flash photolysis of water are analyzed on a computer. (MLH)

Describes an undergraduate experiment that provides instruction in nuclear magnetic resonance (NMR) spectroscopy, reaction rates, and the application of mathematical procedures. (MLH)

Describes experiments used to illustrate the kinetics of reversible chemical reaction. (SL)

Describes an experiment in which the iodonation of aniline reaction is shown to undergo catalysis in solution of sodium lauryl sulfate which forms micelles with negatively charged pseudo surfaces. (MLH)

A device which provides an inexpensive means for making precise studies of the kinetics of gas molecules is discussed. Two experiments are described: (1) Measurement of the vibrational relaxation time of gas molecules and (2) determination of intermolecular forces in molecules. (Author/DF)

Describes an experiment studying a free falling object which reaches terminal velocity quickly due to air resistance. The mathematical analysis includes some calculus. (TS)
