The Chemistry of Paper Preservation Henry A. Carter
This article examines the applications of chemistry to paper preservation. The acid-catalyzed hydrolysis of cellulose accounts for the deterioration of paper in library books and other written records. To combat this threat to our written heritage, new permanent papers have been developed that are relatively chemically stable and undergo a very slow rate of deterioration.

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.

Let Us Give Lewis Acid–Base Theory the Priority It Deserves Alan A. Shaffer
The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

Was Markovnikov's Rule an Inspired Guess? Peter Hughes
A study of 19th century literature shows that neither Markovnikov nor any of his contemporaries carried out the reactions often attributed to himthe addition of hydrogen bromide or hydrogen chloride to propene. Since there is little evidence for Markovnikov's rule in his 1870 article, it is likely that it was more of an inspired guess than a rational conclusion.

Textbook Deficiencies: Ambiguities in Chemical Kinetics Rates and Rate Constants Keith T. Quisenberry and Joel Tellinghuisen
Recommends that textbook authors make it clear that (i) the reaction rate and rate constant cannot be defined unambiguously without explicitly stating the reaction for which they apply and therefore (ii) the relation between the half-life, which is a physical property of the reaction system, and the rate constant depends upon how the reaction is written.

The Addition of Bromine to 1,2-Diphenylethene Judith C. Amburgey-Peters and LeRoy W. Haynes
We investigated the reaction of (Z)-1,2-diphenylethene (cis-stilbene) with various brominating reagents and solvents following directions in standard organic chemistry manuals. We were particularly interested in learning which combination of brominating reagent and solvent gave the best yield of (d,l)-1,2-dibromo-1,2-diphenylethane without the formation of significant amounts of meso-1,2-dibromo-1,2-diphenylethane, which is essentially the sole product from the reaction of bromine with (E)-1,2-diphenylethene (trans-stilbene). Based on the results from the standard preparatory methods, some permutations of solvent and brominating reagent were tried.

An Analogy to Help Students Understand Reaction Orders Charles J. Marzzacco
This article describes a simple analogy to help students understand the concept of the rate law for a chemical reaction. The analogy involves the mathematical relationships between various characteristics of a cube and the length of its edge.

Mechanism Templates: Lecture Aids for Effective Presentation of Mechanism in Introductory Organic Chemistry Brian J. McNelis
To promote active student learning of mechanism in introductory organic chemistry, hand-outs have been developed with incomplete structures for reaction processes depicted, which are called mechanism templates. The key to these lecture aids is to provide only enough detail in the diagram to facilitate notetaking, ensuring that these templates are dynamic learning tools that must be utilized by an engaged and alert student.

A Closer Look at the Addition of Equations and Reactions Damon Diemente
Chemists occasionally find it convenient or even necessary to express an overall reaction as the sum of two or more component reactions. A close examination, however, reveals that the resemblance between chemical algebraic equations is entirely superficial, and that the real meaning of addition in chemical equations is subtle and varies from case to case. In high-school courses, students are likely to encounter the addition of equations in thermochemistry, in electrochemistry, and in kinetics.

A Kinetics Experiment To Demonstrate the Role of a Catalyst in a Chemical Reaction: A Versatile Exercise for General or Physical Chemistry Students Christine L. Copper and Edward Koubek
By modifying the iodine clock reaction, students can use the initial rate method to observe the role of a catalyst in a chemical reaction via activation energy calculations and evaluate a proposed mechanism. They can also determine the order with respect to each reactant and the rate constants of the noncatalyzed and catalyzed reactions.

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.
