Physical Chemistry I

Course Code: B32007Y-01

Course Name: Physical Chemistry I

Credits: 2.0

Pre-requisite: Chemical principle

Course Description:

"Physical Chemistry" is the subject which studies the principles, rules and methods of the chemical behavior of the material system. It is the theoretical basis of chemistry and other subjects that study the material change at the molecular level. Therefore, physical chemistry is one of the important core courses of the chemistry department. Physical chemistry is a science that explores the basic principles of chemical change from the connection between physical phenomenon and chemical phenomenon, and it mainly uses physical methods in experiments.

As a branch of chemistry, the main task of physical chemistry is to explore and solve scientific problems in the following aspects:

  1. the direction and the limit of chemical change
  2. the rate and the basic problems of chemical reaction
  3. the relationship between material structure and properties

According to the current curriculum in our country, the basic physical chemistry mainly solves the former two scientific problems, the latter is solved by structural chemistry and quantum chemistry.

Physical ChemistryI mainly teaches the basis and application of chemical thermodynamics and statistical thermodynamics.The purpose of teaching is letting students understand the thinking method, connotation and extension, characteristics and application of physical chemistry etc, and researching the equilibrium state information, the direction and limit of the material change with the method of thermodynamics and statistical thermodynamics. This provides the necessary foundation for other related courses.

In the teaching process, this course will introduce the source of physical chemistry and the knowledge of related disciplines (especially the knowledge of Theoretical Physics).Through the introduction and studying of the professional knowledge of this course, students should understand the cross-direction theoretical basis and their interrelation of physical chemistry, increasing the interest of students in various disciplines that they have mastered or are about to learn, promoting students to consciously associate the theory, knowledge and technology of various disciplines rather than isolate them. This course focuses on the basic theory, basic concepts and classical methods in physical chemistry, to help students develop a rigorous thinking and style and build a strict concept of physical chemistry. In addition, this course will teach the extension of physical chemistry, appropriately teach some knowledge and progress about the physical chemistry research, especially the leading edge, latest developments and achievements of the physical chemistry research, broadening the horizons of students, making students master the methods and ideas to analyze and solve problems in physical chemistry, and lay a solid foundation for further study.

The main content of Physical ChemistryI includes: Gas, the first law of thermodynamics, the second law of thermodynamics, the thermodynamics of multicomponent systems and its application in solution, phase equilibria, chemical equilibrium, and the fundamentals of statistical thermodynamics.
