Interactive Java Based Web Site For Teaching Chemical Reaction Stoichiometry

Chemical reaction stoichiometry (CRS) is a branch of chemical stoichiometry dealing with the constraints, in the form of chemical equations, placed on changes in the composition of a closed reacting system by the requirement for conservation of the amount of each atomic species. This simple conservation concept has far-reaching consequences for all of chemistry and chemical engineering, including reaction kinetics and reactor design, reaction equilibrium, and reaction “book-keeping” in general. If chemical equations are to be used to express this concept, it is important to have a universal, systematic method for generating a proper set for any system under consideration. However, many methods currently in use, particularly in introductory teaching, do not properly or fully exploit the concept, and may give incomplete or misleading results; their scope is very limited, rendering them obsolete for general use.
