Introduces a pictorial, intuitive approach that allows the teaching of thermodynamics equilibrium in an introductory college physics course. (GA)

The Briggs-Haldane assumption is used as the basis for the development of a kinetic model for enzyme catalysis. An alternative definition of the steady state and examples of realistic mechanisms are provided. (KR)

Presents eight historical consensus models for teaching chemical kinetics. Models put forth by teachers and textbooks in a Brazilian secondary classroom were analyzed and discussed and found to be hybrids of the historical models. The existence of hybrid models in science teaching is proposed as a new component in science teachers' training…

Describes four cases for which simulation techniques can be used to analyze the kinetics of the chemical system. Included are series first-order and enzyme kinetics. (MA)

Presented is a possible approach to the classroom treatment of enzyme kinetics at the two-substrate level. Areas discussed include single substrate cases, two substrate cases, Cleland's rules, dead end inhibition, inhibitor complexing with more than one enzyme form, and product inhibition. (JN)

This paper reports an experiment in the teaching of the kinetic molecular theory to nonscience majors by the inquiry method. It allows the student to develop an essentially correct view of gases, liquids, and solids on the atomic or molecular level, and illustrates how one can draw conclusions about the molecular level by simple visual…

Proposes an approach to chemical kinetics and mechanism using statistical games, illustrating its use in monomolecular, catalytic, autocatalytic, consecutive, and equilibrium reactions. Major features of the games are also outlined and discussed. (JN)

Various aspects of chemical equilibrium were discussed in six papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). These include student problems in understanding hydrolysis, helping students discover/uncover topics, equilibrium demonstrations, instructional strategies, and flaws to kinetic…

Describes the graphing calculator as a new graphical approach to standard physics problems. Presents a collision problem to illustrate its use. (JRH)

Osmotic pressure proves to be a useful topic for illustrating the disputes brought to bear on the chemistry profession when mathematics was introduced into its discipline. Some chemists of the late 19th century thought that the introduction of mathematics would destroy that "chemical feeling" or "experience" so necessary to the practice of…

A reaction kinetics experiment for the chemical engineering undergraduate laboratory course was developed in which in-situ Fourier Transfer Infrared spectroscopy was used to measure reactant and product concentrations. The kinetics of the hydrolysis of acetic anhydride was determined by experiments carried out in a batch reactor. The results…

A secondary school teacher presents his teaching methodology concerning the kinetic theory of gases and gas laws. (CP)
