Kimax: A Maxima package for analysis of reaction kinetics

In this study, we develop a chemical reaction analysis package called "Kimax" using Maxima, a GNU free symbolic algebra system. Kimax derives and analyzes differential equations, also called rate equations, corresponding to a large class of chemical reactions of both reversible and irreversible types. At first, it enables user to observe differential equation or system of equations corresponding to a given reaction, and then obtains and displays desired solution components as time evolves. In addition to all these, Kimax is able to analyze reactions with different initial concentrations by estimating the reaction rate constant with the assumed product concentration value obtained as an experimental result for single reactant and irreversible reactions.
