The Correlation of Binary Acid Strengths with Molecular Properties in First-Year Chemistry Travis D. Fridgen This article replaces contradictory explanations for the strengths of different binary acids in first-year chemistry textbooks with a single explanation that uses a BornHaber cycle involving homolyic bond dissociation energies, electron affinities, and ion solvation enthalpies to rationalize trends in the strengths of all binary acids.

Teaching Entropy Analysis in the First-Year High School Course and Beyond Thomas H. Bindel A 16-day teaching unit is presented that develops chemical thermodynamics at the introductory high school level and beyond from exclusively an entropy viewpoint referred to as entropy analysis. Many concepts are presented, such as: entropy, spontaneity, the second law of thermodynamics, qualitative and quantitative entropy analysis, extent of reaction, thermodynamic equilibrium, coupled equilibria, and Gibbs free energy. Entropy is presented in a nontraditional way, using energy dispersal. Bindel, Thomas H. J. Chem. Educ. 2004, 81, 1585.

Entropy, Disorder, and Freezing Brian B. Laird It is argued that the usual view that entropy is a measure of "disorder" is problematic and that there exist systems at high density, for which packing considerations dominate, where a spatially ordered state has a higher entropy than a disordered one.

Vapor Pressure Lowering by Nonvolatile Solutes Gavin D. Peckham This short article highlights a fundamental error that is entrenched in introductory chemistry textbooks. It is true that the addition of a nonvolatile solute causes a lowering in the vapor pressure of a solution. The error lies in attributing this vapor pressure lowering to the "blocking" of surface sites by nonvolatile particles. This is a totally fallacious argument for a number of reasons and the true explanation is to be found in the entropy changes that occur as a nonvolatile solute is added to a solution. Peckham, Gavin D. J. Chem. Educ. 1998, 75, 787.
