**Introduction to course**

- Elementary Mathematics
- Physical States of Mater
- Atomic Structure
- Chemical Thermodynamics
- Chemical Equilibrium
- Solutions
- Chemical Kinetics
- Electrochemistry

**Course pre-requisites (if any)**

- The prerequisites is the Physical Chemistry (CHEM 181), Inorganic Chemistry (CHEM 161) in minimum grade “C” or better.

**Learning outcomes**

- The subject physical chemistry covers basic scientific knowledge and its application in the field of biotechnology. Students will acquire knowledge to enable themselves to understand the fundamental principles and laws of thermodynamics and chemical equilibria and to investigate the physical properties of ideal/non-ideal binary solutions. Students will also be able to study the rates of reactions and perform related calculations.
