Physical Chemistry is a foundational course at Tongji School of Pharmcy, HUST. It is a very broad subject, and plays an important role in the understanding of core theories in pharmaceutical sciences, particularly for pharmaceutics, physical organics, computational drug design and development, etc.This introductory course of physical chemistry includes laboratory practices and covers chemical thermodynamicsand chemical kinetics.
Theory: 64 Hours; Laboratoryexperiments: 32 Hours.
The prerequisites are algebra,calculus of single variable functions, general chemistry.

After completing this course, students should be able to carry out mathematical calculations based on fundamental physical chemistry concepts and definitions, through which they could evaluate heat effect of chemical reactions, determine physical properties of phase transitions as well as predict the direction of chemical or physical processes. After participating laboratory experiments students should be familiar with tools used by physical chemists and be able to perform data processing and error analysis.
