Three questions and answers involving chemistry are presented. Question one involves elimination of reptiles from the earth; the second considers chemical effects on taste acuity; the third relates to muzzle velocity of a projectile fired from a gun and temperatures inside the cartridge. (MLH)

Presents an instructional approach to be used in the teaching of equilibrium processes. (CP)

This paper is concerned with the thermodynamic formulation of the Activated Complex Theory (otherwise called Transition State Theory or Absolute Rate Theory). (Author/CP)

Suggest the use of oxidation state diagrams in teaching general chemistry in order to provide a realistic presentation of thermodynamics and inorganic chemistry. (SL)

Presents a study designed to evaluate the influence of temperature on the equilibrium and the structural changes of the complexes interpreted in terms of ligand field theory. (CW)

Draws a distinction between the terms "heat and work" and "energy" in terms of the teaching of thermodynamics. Gives examples using enthalpy and constant pressure processes, free energy and spontaneity, and free energy and available mechanical energy. Concludes that there is no thermodynamic role for the terms "heat"…

Describes three examination questions which could be used in college chemistry courses. Discusses each problem and gives acceptable solutions. Problems include: "A Multi-Topic Problem for General Chemistry"; "Consumption of Air by Biuret Reagent--a Question Involving Experimental Design"; and "An Instructive Problem in Heterogeneous Equilibrium."…

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

Demonstrates, with a set of definitive examples, how polymer principles can be introduced into the first undergraduate physical chemistry course in a very natural way. The intent is to encourage introduction of polymer-related material into conventional physical chemistry courses without sacrificing any rigor associated with such courses. (JN)

Presents a largely experimental approach to the concept of mixed potentials, pointing out the close parallel that exists between equilibrium potentials. Describes several important examples of mixed potentials, providing current-voltage and polarization curves and half reactions as examples. Includes a discussion of corrosion reactions and…

Considers the thermodynamic limitation to the efficiency with which light energy can be converted into work, indicating that no single chemical system converting solar energy into useful work can be very efficient. Also indicates that if solar energy is absorbed as heat for heating purposes, it is almost completely used. (JN)

Discusses a criterion for determining when to use the simplifying assumption that the amount of weak acid or base dissociated is negligible compared with the total concentration. (MLH)

Presents demonstrations concerning the thermodynamic properties of rubber elasticity and simultaneous reactions of acetone. (MLH)

The First Law of Thermodynamics is discussed based on childhood experiences such as playing with seesaws, falling balls, thrown balls, bouncing balls, friction, combustion, and arithmetic. (DF)
