Contents to Physical Chemistry Physical Chemistry contains three major parts--- thermodynamics,kinetics and structure chemistry. .Thermodynamics deals with the interconversion of various kinds of energy and the changes in physical properties that are involved. (1)The first law of thermodynamics deals with the amount of work that can be done by a chemical or physical process and the amount of heat that is absorbed or evolved. (2)The second law of thermodynamics deals with the natural direction of processes and the question of whether a given chemical reaction can occur by itself.
