Graphing Calculator Strategies for Solving Chemical Equilibrium Problems

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.
