Visualizing the Transition State: A Hands-on Approach to the Arrhenius Equation  Thomas S. Kuntzleman, Matthew S. Swanson, and Deborah K. Sayers
Pennies and dice are used to simulate the kinetics of two irreversible "reactions" with a hands-on, Monte Carlo approach. Arrhenius plots of the data generated yield activation energies comparable to assigned values and pre-exponential factors close to what would be expected based on the probability of a "reactant" achieving the correct orientation for conversion into "product". A comparison of the values obtained for the pre-exponential factors for the different simulations allows students to semi-quantitatively discuss the orientational requirement that is contained within this factor.

Rotational Mobility in a Crystal Studied by Dielectric Relaxation Spectroscopy. An Experiment for the Physical Chemistry Laboratory  Madalena S. C. Dionísio, Hermínio P. Diogo, J. P. S. Farinha, and Joaquim J. Moura-Ramos
In this article we present a laboratory experiment for an undergraduate physical chemistry course. The purpose of this experiment is the study of molecular mobility in a crystal using the technique of dielectric relaxation spectroscopy. The experiment illustrates important physical chemistry concepts. The background of the experimental technique deals with the concepts of orientational and induced polarization and frequency-dependent relative permittivity (or dielectric constant). The kinetic concepts of temperature-dependent relaxation time, activation energy, and activation entropy are involved in the concept of molecular mobility.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy  Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz
A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week.

A simple, inexpensive, water-jacketed cuvette for the Spectronic 20 is described.

As a demonstration of the cuvette's utility, we used the cuvette for the determination of the activation energy for the reaction between crystal violet and hydroxide ion. However, the cuvette may prove useful in a variety of applications in which a sample must be thermostated within a spectrophotometer.

It can and does, however, affect the kinetics-the rate at which a new equilibrium is established.

Why the Arrhenius Equation Is Always in the "Exponentially Increasing" Region in Chemical Kinetic Studies  Harvey F. Carroll
The Arrhenius equation in chemical kinetics, k = Ae-Ea/RT, has, as T gets larger, an inflection point where it changes from an "exponentially increasing" curve to one approaching an asymptote of A. The inflection point occurs at T = Ea/2R. For any activation energy, the inflection point occurs at such a high temperature that chemical kinetic studies would not be possible. Thus, the Arrhenius equation always appears to be exponentially increasing in any chemical kinetic studies of interest.

Limiting Reagent and Kinetics: Social Implications and Malthus' Prediction  L. H. Holmes Jr.
Robert Malthus predicted in the early 1800s that man would outstrip his food supply. The amount of carbon on earth is the ultimate limiting reagent for the number of people the earth can have and in the sense that carbon is our "food", Malthus was right. However, the land area of the earth is a "limiting reagent" that will limit our population before carbon does. These concepts are discussed in the context of limiting reagents and chemical kinetics to show that if the rate of increase of population remains at what it is now, we have less than a thousand years to "solve" the problem.

Why Don't Things Go Wrong More Often? Activation Energies: Maxwell's Angels, Obstacles to Murphy's Law  Frank L. Lambert
The micro-complexity of fracturing utilitarian or beautiful objects prevents assigning a characteristic activation energy even to chemically identical artifacts. Nevertheless, a qualitative EACT SOLID can be developed. Its surmounting is correlated with the radical drop in human valuation of an object when it is broken.

A Laboratory Experiment Investigating Different Aspects of Catalase Activity in an Inquiry - Based Approach  Doris R. Kimbrough, Mary Ann Magoun, Meg Langfur
The action of the enzyme catalase on aqueous hydrogen peroxide to generate oxygen gas is a well-established demonstration. Catalase is typically obtained by aqueous extraction of a potato, and the potato extract is mixed together with 3% hydrogen peroxide. The oxygen that is produced can be collected over water. Variations on the procedure can demonstrate the dependence of catalytic activity on temperature or the presence of inhibitors.
