AIM
To understand important concepts in physical chemistry.
OBJECTIVES
To understand the different states of matter, theoretical principles governing the
solid, liquid , mesomorphic and solid states and to know methods for experimental
determination of characteristic properties of the states.
To understand the principles of thermodynamics in deciding the spontaneity of
reactions and energy changes involved in physical and chemical processes.
To understand the principles of photochemistry and catalysis.
