Course Objectives:
This course gives and overall view on the various areas related to physical chemistry like chemical kinetics, colloidal state, adsorption
etc which have great relevance in practical applications. The practical course is designed for imparting the knowledge of general
principles of physical chemistry through experimentation. It involves the use of instruments also that helps the students to correlate the
classical and newer approach.
Prerequisites:
