Physical Chemistry 1 Mehdi Irani

Physical Chemistry I (B.Sc. Course)

Course Prerequisites:

· General Chemistry II

· Calculus

· Fundamental Physics I

Course Description

This course provides an introduction to the physical foundations of chemical phenomena, focusing on thermodynamics, kinetic theory, and gas behavior. It emphasizes the theoretical principles behind energy changes, molecular motion, and equilibrium, aiming to justify chemical behavior from a physical chemistry standpoint. Both conceptual understanding and problem-solving are emphasized throughout the course.
