Chemistry Time: Factors Affecting the Rate of a Chemical Reaction
This activity can be used to introduce a unit on chemical kinetics, but it is simple enough to be used in a discussion of chemical reactions or experimental methods/procedures during the first weeks of the semester. The activity involves reacting bicarbonate with acid, a reaction with practical applications in everyday life.

Audience-Appropriate Analogies: Collision Theory Kent W. Piepgrass
This article presents two new analogies for collision theory based on arcade games and on the interactions between salesclerks and customers in a store. The uses, limitations, and possible extensions of the analogies are discussed.

Small-Scale Kinetic Study of the Catalyzed Decomposition of Hydrogen Peroxide Ronald O. Ragsdale, Jan C. Vanderhooft , and Arden P. Zipp
The decomposition of hydrogen peroxide can be studied directly and quickly by determining the rate of formation of oxygen bubbles produced. This experiment, like the iodine clock reaction, provides quantitative measurements for a general chemistry course.

Reduction of permanganate: A kinetics demonstration for general chemistry Steffel, Margaret J.
Using the reduction of MnO4- to Mn2+ in aqueous solution to demonstrate the four factors that control reaction rates in solution: the natures of the reactants, concentrations of the reactants, temperature, and the presence of a catalyst.
