A Conceptual Approach to Limiting-Reagent Problems
Sostarecz, Michael C.; Sostarecz, Audra Goach
Journal of Chemical Education, v89 n9 p1148-1151 Sep 2012
A solid foundation of chemistry principles is only gained through a true comprehension of the material as opposed to pure memorization. One of the most fundamental concepts in chemistry is that of determining the amount of product formed in a chemical reaction when one of the reactants is limiting. To increase students' comprehension of this important concept, a conceptual approach is presented that is tangible for limiting-reagent problems on the molecular level and extends directly to typical examples that would be encountered in a classroom or laboratory setting. To accommodate visual learners, a graphical methodology is incorporated that determines the limiting reagent as the reactant that is exhausted first while simultaneously finding the amounts of the excess reagents and products. (Contains 2 tables and 3 figures.)
