1:-States of Matter:- Gases
and Liquids: Three states of matter, intermolecular interactions, types of
bonding, melting and boiling points, role of gas laws in elucidating the
concept of the molecule, Boyle's law, Charles law, Gay Lussac's law, Avogadro's
law, ideal behaviour, empirical derivation of gas equation, Avogadro's number,
ideal gas equation and deviation from ideal behaviour.
2:-Chemical Thermodynamics:- Concepts
of System and types of systems, surroundings, work, heat, energy, extensive and
intensive properties, state functions. H, Hess's lawDU and DFirst law of thermodynamics -internal
energy and enthalpy, measurement of of
constant heat summation, enthalpy of bond dissociation, combustion, formation,
atomization, sublimation, phase transition, ionization, solution and dilution.
Second law of Thermodynamics (brief introduction) Introduction of entropy as a
state function, Gibb's energy change for spontaneous and nonspontaneous
processes. Third law of thermodynamics (brief introduction).
3:-Equilibrium:- Equilibrium in physical and chemical processes, dynamic
nature of equilibrium, law of mass action, equilibrium constant, factors
affecting equilibrium - Le Chatelier's principle, ionic equilibrium- ionization
of acids and bases, strong and weak electrolytes, degree of ionization,
ionization of poly basic acids, acid strength, concept of pH, buffer solution,
solubility product, common ion effect (with illustrative examples).

occurrence, anomalous properties of the first element of each group, diagonal
relationship, trends in the variation of properties (such as ionization
enthalpy, atomic and ionic radii), trends in chemical reactivity with oxygen,
water, hydrogen and halogens, uses.
