Kinetics and Reaction Engineering
|Course code CHEE4320||Units 10||Level 4000||Faculty of Engineering and Built EnvironmentSchool of Engineering|
Introduces students to the application of kinetics and reaction engineering in chemical engineering processes. The course will not only serve as an introduction to the fundamental principles of kinetics and reaction engineering, but also to the practical application of the technology in industry.
Available in 2015
