Graphing Calculator Strategies for Solving Chemical Equilibrium Problems
Henry Donato Jr.
Department of Chemistry & Biochemistry, College of Charleston, Charleston, SC 29424
Cover
May 1999
Vol. 76 No. 5
p. 632
Abstract
Polynomial equations arising from analysis of the chemical equilibrium state present computational difficulties for many introductory chemistry students. A general method for finding the roots of these polynomial equations using the ubiquitous and inexpensive graphing calculator is presented. It is suggested that important reactions, which are not discussed in introductory chemistry courses because of computational considerations, may now be discussed. Also, complete treatments of equilibrium systems may be given so that students will not have to deal with a complex array of approximate methods.

See Letter re: this article.
Supplement
Detailed instructions for implementing these strategies on TI-85, TI-86, and Ti-92 calculators are available as a pdf file, which can be accessed using Acrobat Reader, or as three Microsoft Word documents that have been compressed into sit (for Macintosh) and zip (for Windows) files.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
