Course Information

About this Course

The course is an introductory course to physical chemistry which covers the areas of thermochemistry, thermodynamic, electrochemistry, chemical kinetics, phase equilibrium, colloids and surface chemistry. The lecture session is used to discuss and relates the laws, principles and theories in physical chemistry. The outcomes will be assessed through paper examination, teats and quizzes, laboratory exercises and written laboratory reports.
