The design idea and design flow of the simulation software on the complex reaction kinetics are introduced in this article. Firstly, the total framework of the software was determined by the goal and function of the software; Secondly, the manuscript was written, the multimedia material was made and the computational programs were designed, the examples of making multimedia material by Photoshop and Flash are introduced, moreover, the thinking and method of program is introduced; Finally, The material such as text, images, sounds, animation is integrated by Authorware. The simulation software has friendly interface and simple operation, it can be used as a computational tool in studying chemical kinetics, in addition, the software can be assisted in the teaching such as physical chemistry and reaction engineering.
The mathematical model on acid-base titration was established by using analytical chemistry theory; therefore the author designed a program to solve the model by using of Visual Basic language. The program can not only calculate the pH Value of the acid-base titration solution, choose the appropriate indicator, calculate the endpoint error and judge the feasibility of the titration, but also can draw the curve of the acid-base titration.
Based on the mass action law, the kinetics equation of the complex consecutive reaction was established in the form of first-order ordinary differential equations. Therefore; a program was designed by the Visual Basic language and the theory of the numerical calculation to solve the ordinary differential equations. In the end, the reaction process of the complex consecutive reaction was simulated by the powerful plot function of the Visual Basic language.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
