The course gives the overview of the chemical reaction from the macroscopic and microscopic points of view. First of all the basic concepts, i.e. the reaction rate, reaction rate constant, rate equation, reaction order and molecularity, are given. Then, the characteristics of the first-order and second-order reactions is shown. From the microscopic points of view the transition state theory on the rate constant is discussed. From more microscopic points of view the concepts of the reaction cross section is introduced instead of the rate constant , and the relation between the reaction rate constant and reaction cross section is discussed.
The aim of this course is getting the basic recipe for understnading chemical reactions.
By the end of this course students will be able to understand,
chemical reactions from the macroscopic points of view and microscopic points of view, i.e. atomic and molecular picture,
Reaction kinetics, Transition state theory
