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

Describes the genesis, development, implementation, and evaluation of a graduate level kinetics course based on selected influential papers in chemical reaction engineering. (BB)

Gives a perturbation analysis to recurrence effects of the spring pendulum. The recurrence depends on two conservation laws which determine the motion in an intermediate region; oscillations outside this region are unstable and must return. Gives the relation to Fermi-Pasta-Ulam problem together with the explicit solution. (Author/GA)

A simulation experiment for the dissolution kinetics of steroids is described whose goals are to demonstrate the characteristics of the physical-chemical model for dissolution and to relate the physical-chemical model to the potential therapeutic availability of the drug. Computational details are given. (LBH)

Describes a recording gas microvolumeter constructed to carry out sensitive studies of the kinetics of photodecomposition of water. (SL)

Describes experiments used to illustrate the kinetics of reversible chemical reaction. (SL)

Traditional undergraduate courses in gas kinetic theory encourage the view that in all collisions between a gas atom and a surface, the angle of incidence of the gas atom equals its angle of reflection. This article illustrates and explains the incorrectness in assuming specular reflection and zero dwell time. (Author/MA)

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

Describes a practical and visual way of extending the concept of symmetry present in nature to the quantum structure of molecules. (SL)

Presents a simple method for deriving steady state rate equations for first-order and pseudo-first-order reactions. (SL)

Proposes use of an operative procedure (for studying chemical reactions in solution by nonisothermic methods) employing an electronic device that is inexpensive and easy to build and that gives excellent results. A diagram of the temperature controller in operation and a circuit diagram for the motor are included. (JN)

Discusses theory, procedures, and results for an experiment which demonstrates the application of basic physics to chemical problems. The experiment involves the adiabatic process, in which polymerization carried out in a vacuum flask is compared to the theoretical prediction of the model with the temperature-time curve obtained in practice. (JN)

Reports on the adaptation of a kinetic method of analysis of metal ions for use in an undergraduate teaching laboratory. Background information, procedures used, and analysis of typical results obtained are provided. (JN)

Oxidation kinetics in metals and the role defects play in diffusion-controlled reactions are discussed as background for a junior/senior-level experiment in the physical or inorganic chemistry laboratory. Procedures used and typical data obtained are provided for the experiment. (JN)

Describes a user-friendly computer program that will analyze the data from one kinetics experiment for 84 different rate laws (sets of partial orders). Information on obtaining the program (written in VAX-Basic and implemented on a VAX-780 computer), its instruction, and related programs are included. (JN)
