The project was prepared by using the knowledge obtained from the study from the Department of Chemical and Materials Engineering at the second year students in chemistry, chemical engineering applications. Operating in the laboratory. We are interested in the study of chemical kinetics The reaction Batch a the% conversion constants of reactions. And the reaction This project will change from Batch reactor as a reaction in Reactor, we use silicone tube is Reactor, to study for% conversion and constants of reactions in Reactor at different characteristics that Reactor does. % conversion are more common. The Reactor, we will compare between. Pipe sizes are equal Different lengths with different sized pipes. The same length
