Textbook Deficiencies: Ambiguities in Chemical Kinetics Rates and Rate Constants Keith T. Quisenberry and Joel Tellinghuisen Recommends that textbook authors make it clear that (i) the reaction rate and rate constant cannot be defined unambiguously without explicitly stating the reaction for which they apply and therefore (ii) the relation between the half-life, which is a physical property of the reaction system, and the rate constant depends upon how the reaction is written. Quisenberry, Keith T.; Tellinghuisen, Joel. J. Chem. Educ. 2006, 83, 510.

Promoting Graphical Thinking: Using Temperature and a Graphing Calculator To Teach Kinetics Concepts José E. Cortés-Figueroa and Deborah A. Moore-Russo A Calculator-Based Laboratory (CBL) System, a graphing calculator, and a cooling piece of metal are used in a classroom demonstration to teach key concepts of a first-order chemical reaction. This activity promotes graphical thinking and permits student-centered instruction where the students explore concepts and discover how simple mathematical equations model observable facts (data).
