Applying the Reaction Table Method for Chemical Reaction Problems (Stoichiometry and Equilibrium)
Steven F. Watkins
Department of Chemistry, Louisiana State University, Baton Rouge, LA 70803

June 2003
Vol. 80 No. 6
p. 658
Abstract
Stoichiometry and equilibrium problems, quantitative settings of the balanced chemical reaction, are universally difficult for beginning- and intermediate-chemistry students. The traditional approach is to introduce each reaction "type" with an apparently ad hoc analytical strategy and calculational procedure. Such an approach compels students to differentiate and compartmentalize these ideas and techniques. A systematic and integrated approach to the analysis and solution of all types of stoichiometry and equilibrium problems is presented. The Reaction Table is a spreadsheet format that contains all numerical and algebraic data relevant to the problem and provides a single calculational structure within which a consistent set of analytical and computational techniques can be developed. The method helps students recognize common concepts, analyze problems, organize calculations, draw logical inferences, recognize distracters, validate answers, and proceed to resolution with confidence and accuracy.
Supplement
Sample problems and analyses are available.
