Abstract

The Texas Instruments TI-89 calculator is an advanced scientific calculator that has both graphing and programming capabilities, and advanced-mathematics software. In this article the TI-89 has been used for solving a variety of problems in physical chemistry. The applications in this paper include calculations with units, solving higher-order equations that are set up in chemical equilibrium problems, differential- and integral-calculus-based calculations in thermodynamics and quantum mechanics, numerical and analytic solutions of first-order differential equations in chemical kinetics, and regression analysis of data collected in a kinetics experiment. The appropriate calculator keystrokes are included for all the examples in this paper. Many complex and interesting problems can be studied with relative ease, thus allowing teachers to introduce modern scientific techniques in the classroom.
