Analysis of functions' behavior. Next example is analysis of dividing of chemical reactor with ideal mixing into sections. The efficiency of such reactor may be enhanced by dividing into sections. But at high y it is significant and 3-4 sections is enough. To find the answer to various problems of physical chemistry we must solve systems of differential equations.
Obvious example is the analysis of chemical kinetics of complex chemical reaction.
Along using this program student write chemical equation for each simple reaction and value of rate constant of this reaction. After solving the system of differential equations it is possible to receive graph for time dependence of the concentrations for up to 15 substances involved in maximum 10 reactions and table of current concentrations. This program also allows us to determine the values of rate constants using experimental data of current concentrations. They may see that for this system cited equation satisfactory describes system behavior. Every student draws phase diagram of water very easily.
