Physical Chemistry (I)

2025-10-21 01:17:28 |

This course will begin with introducing the principles of heat transfer between systems and surroundings, and the energy conversation. Then the study of the laws of thermodynamics. 

The student will be then taught how to use the principles of thermodynamics in determining the direction of a spontaneous process. And to use thermodynamics equations in describing a particular system. The student will be trained to plot and interpret phase diagrams and to study chemical equilibrium using the basic principles of thermodynamics.
