Defines and investigates a moment of inertia tensor for a quantum mechanical wave packet. (SL)

Presents a method for simplifying calculations in quantum chemistry by calculating molecular energy from the electrostatic theorem. (SL)

Presents a completely arithmetic development of Newtonian dynamics in which all classical conservation laws are valid and all equations are in forms amenable to high-speed digital computer computation. (SL)

Various examples of open-ended problems and ways to obtain them are presented. Suggestions for incorporating open-ended problems and some of the benefits and difficulties encountered by teachers and students are discussed. Examples are from courses on mass and energy balances, communications, kinetics and ideal reactors, and reactor design. (KR)

Discusses solutions to the problem of maximizing the range of a projectile. Presents three references that solve the problem with and without the use of calculus. Offers a fourth solution suitable for introductory physics courses that relies more on trigonometry and the geometry of the problem. (MDH)

Provides a simplified, synoptic overview of the area of thermodynamics, enumerating and explaining the four basic laws, and introducing the mathematics involved in a stepwise fashion. Discusses such basic tools of thermodynamics as enthalpy, entropy, Helmholtz free energy, and Gibbs free energy, and their uses in problem solving. (JM)

Details how a spreadsheet with graphics capabilities can be used to illustrate enzyme kinetics and explain how computer simulation of a reaction mechanism is accomplished. (DDR)

Presented are several simple kinetic systems together with the spreadsheets used to solve them. A set of exercises in chemical kinetics appropriate for an introductory course in physical chemistry is given. Error propagation calculations with experimental data are illustrated. (CW)

Although students' misconceptions about the concept of chemical equilibrium has been the focus of numerous investigations, few have investigated students' systematic errors when solving equilibrium problems at the college level. Students (n=189) enrolled in the second semester of a first year chemistry course for science and engineering majors at…
