Reaction Progress is a program that was developed to aid students in their understanding of Chemical Stoichiometry and Limiting Reactants. It provides a simple interface where the user can input a reaction and see how changes in the extent of reaction will affect the amounts of the reagents.

The program works best in HTML5 compliant browsers such as the latest versions of Google Chrome, Safari, or Opera.

Equilibrator is designed to help students in introductory chemistry classes understand the relationship between Extent of Reaction, ξ, and Gibbs (free) Energy, G. It allows the user to modify the reaction conditions and instantly see the effect on the reaction.
