Physical chemistry-II is designed for the students of BS-VI to make the students capable of understanding in 3 important fields (Quantum Chemistry, Statistical Thermodynamics & Electrochemistry) of Physical Chemistry. The objective includes to make the students understand the foundation of Quantum Chemistry along with derivation of Schrodinger Wave Equation, interpertation of wave function and its mathematical requirements and the application of knowledge to understand the structure of atom&molecules and a  glance into sub-atomic phenomenon, properties and occurances. This basic knowledge leads further to understand the properties of molecules and their reactions. Moreover concepts of observable, functions and operator and their properties are also part of course. Statistical thermodynamics gives the knowledge about probibility, stirilings approximation, Boltzman distribution law and partition functions along with its types. Moreover,, the section of Electrochemistry includes concept of conductance of electrolytes. Debye–Huckle equation and limiting law. Ionic strength, weak electrolytes and Debye–Huckle theory. Activity and activity coefficients of electrolytic solutions. Determination of activities. Concentration cells. Determination of e.m.f. of concentration cells with and without transference. Fuel cells and hydrocarbon fuel cells etc.
