Describes a method of flow injection analysis intended for calculation of complex-formation and redox reaction stoichiometries based on a closed-loop configuration. The technique is suitable for use in undergraduate laboratories. Information is provided for equipment, materials, procedures, and sample results. (JM)

Notes that the rigorous kinetic theory, based on the Boltzmann equation, does not yield exact results although some texts claim this to be so. Stresses that they should be presented as approximations with an indication that refinements in the values are possible. (MVL)

Reviews some important properties of the bimolecular reaction between the hydroxyl radical and carbon monoxide. Investigates the kinetics of the reaction, the temperature and pressure dependence of the rate constant, the state-to-state dynamics of the reaction, and the reverse reaction. (MVL)

Describes a simple redox reaction that occurs between potassium permanganate and oxalic acid that can be used to prepare an interesting disappearing ink for demonstrating kinetics for introductory chemistry. Discusses laboratory procedures and factors that influence disappearance times. (CW)

Reports an experimental procedure for studying Einstein's theory of Brownian movement using commercially available latex microspheres and a video camera. Describes how students can monitor sphere motions and determine Avogadro's number. Uses a black and white video camera, microscope, and TV. (ML)

Presents a parallel treatment of the same phenomena by two approaches (steady-state approximation and approximate solution of the appropriate diffusion equation) to clarify the physical meaning of the important radiation boundary condition in the diffusional derivation. (JN)

Heat is defined as a random or nondirected internal energy transfer between different bodies at different temperatures. Work is defined as oriented or nonrandom internal energy transfer. Both heat and work are demonstrated to lead to increases in temperature via interpretations from gas kinetic theory. (JN)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Part l (SE 538 305) covered application of classical thermodynamics, polymer crystallinity, and phase diagrams to teaching physical chemistry. This part covers statistical thermodynamics, conformation, molecular weights, rubber elasticity and viscoelasticity, and kinetics of polymerization. Eight polymer-oriented, multiple-choice test questions…

Background information, apparatus needed, procedures used, and results obtained are provided for a simple kinetic method for the monitoring of adsorption processes. The method, which involved adsorption of crystal violet onto activated carbon, is suitable for classroom and/or research purposes. (JN)

Discusses a simulation on enzyme kinetics based upon the ability of computers to generate random numbers. The program includes: (1) enzyme catalysis in a restricted two-dimensional grid; (2) visual representation of catalysis; and (3) storage and manipulation of data. Suggested applications and conclusions are also discussed. (DH)

Examines mechanisms related to use of N-bromosuccinimide (NBS) for bromination at an allylic position. Also presents derived rate laws for three possible reactions of molecular bromine with an alkene: (1) free radical substitution; (2) free radical addition; and (3) electrophilic addition. (JN)

Kinetic versus thermodynamic control of product formation is discussed in undergraduate textbooks, and journal papers suggest suitable experiments to illustrate this concept. In rationalizing experimental observations, this paper offers a new alternative to that conventionally employed and provides students with an interesting exercise in…

Describes an undergraduate enzyme kinetics experiment which uses bovine erythrocyte carbonic anhydrase, a very stable enzyme commercially available in lyophilized form. Includes background information, reactions involved, procedures used, and the calculation of typical results obtained. (JN)

Background information, procedures, and typical results are provided for an experiment on the decomposition of murexide in acid solution. The experiment, suitable for advanced courses, can be easily performed in a 6-hour laboratory period. (JN)
