ABSTRACT:
The oscillating reactions are the most spectacular and essential for life [1]. All live processes are bases on one or more oscillating reactions [2, 3]. The possibility of periodically altering the concentrations of the reactants, the agents and the product, in space and time, is a result of the autocatalysis. The heartbeat is controlled by an oscillating electrical signal; which is generated by chemical reactions that should be also oscillatory. [4-6]. Other direction is to models the kinetic processes that are involved in chemical reactions [7]. The present paper describes three variants of well the known oscillating reaction models and presents the mathematical equations associated with them. The differential equations are numerically solves and fit with MathCad program.
