SYLLABUS- CHEMICAL ENERGETICS, EQUILIBRIA & FUNCTIONAL GROUP ORGANIC CHEMISTRY-I, Section A: Physical Chemistry-1 (30 Lectures)
Chemical Energetics: Review of thermodynamics and the Laws of Thermodynamics. Important principles and
definitions of thermochemistry. Concept of standard state and standard enthalpies of formations, integral and
differential enthalpies of solution and dilution. Calculation of bond energy, bond dissociation energy and
resonance energy from thermochemical data. Variation of enthalpy of a reaction with temperature – Kirchhoff’s
equation.Statement of Third Law of thermodynamics and calculation of absolute entropies of substances.
(10 Lectures)
Chemical Equilibrium: Free energy change in a chemical reaction. Thermodynamic derivation of the law of
chemical equilibrium. Distinction between DG and DG°, Le Chatelier’s principle. Relationships between K p, Kc
and K for reactions involving ideal gases. x (8 Lectures)
Ionic Equilibria: Strong, moderate and weak electrolytes, degree of ionization, factors affecting degree of
ionization, ionization constant and ionic product of water. Ionization of weak acids and bases, pH scale, common
ion effect. Salt hydrolysis-calculation of hydrolysis constant, degree of hydrolysis and pH for different salts. Buffer
solutions. Solubility and solubility product of sparingly soluble salts – applications of solubility product principle.
(12 Lectures)
