• Resumen

  • College students encounter a variety of first-order phenomena in their mathematics and science courses. Introductory chemistry textbooks that discuss first-order processes, usually in conjunction with chemical kinetics or radioactive decay, stop at single, discrete dose events. Although single-dose situations are important, multiple-dose events, such as taking prescription and nonprescription medicines over a period of time, are familiar, practical applications of kinetics that can be presented to science and nonscience majors without increasing the mathematical demand. Continuous dosing events, such as intravenous drips, are readily accessible to students who have completed a semester or more of calculus. Examples of multiple-dose problems are presented that are appropriate for students taking introductory, general, and physical chemistry courses.
