Abstract

G and S is designed to show Gibbs energy and entropy as a function of extent of reaction. It can be used to determine equilibrium compositions and changes in Gibbs energy and entropy for reactions, and to invite the exploration of differences and relationships between various thermodynamic properties. Changes in the system, surroundings, and universe are all available to show different ways in which the second law of thermodynamics can be used to determine the direction of spontaneous change and the position of equilibrium. It permits quantitative tests of qualitative predictions of the effect on equilibrium position following a change in the conditions.

G and S can be used as a lecture demonstration or as a dry lab for students to explore the interrelationship between Gibbs energy, entropy, and equilibrium. An extensive exercise illustrating many uses of the program is included.
