ChemReaX™ is a free web app for modeling and simulating basic chemical reactions. The software is intended for chemistry students and their teachers at the undergraduate and high school (AP/IB) levels. The ChemReaX simluation platform makes it easy to create sophisticated virtual labs in general chemistry and physical chemistry courses. ChemReaX can be used to experiment with chemical thermodynamics, reaction equilibria, kinetics, and acid-base titration.
It includes thermodynamic properties for over 1200 chemical species, allowing users to construct a virtually unlimited variety of chemical reactions. Or users can choose from over 80 predefined reactions. ChemReaX simulates a given reaction from initial conditions to a final equilibrium state, and accurately models the effects of concentrations, temperature and pressure. It comes with a detailed user guide, tutorials and several ready-to-use virtual lab exercises.
