Introduction To Chemical Thermodynamics And Kinetics

This course will cover classical thermodynamics and kinetics developed to explain a variety of macroscopic physico-chemical phenomena with applications in Chemistry. This course is designed as an introductory level course to the broad area of thermodynamics and kinetics and the lectures will be pitched at the level of undergraduates (both freshman and sophomore level).INTENDED AUDIENCE :BSc/BS/BE/BTech/Int-MSc/Int-MTech 1st or 2nd year students
