To the Memory of My Parnets
Preface
in recent years, the teaching curriculum of Physical Chemistry in many indian
universities has been restructured with a greater emphasis on a theoretical and
conceptual methodology and the applications of the underlying basic concepts and
principles. This shift in the emphasis, as i have observed, has unduly frightened
undergraduates whose performance in Physical Chemistry has been otherwise
generally far from satisfactory. This poor performance is partly because of the
non-availability of a comprehensive textbook which also lays adequate stress on
the logical deduction and solution of numericals and related problems. Naturally,
the students find themselves unduly constrained when they are forced to refer to
various books to collect the necessary reading material.
it is primarily to help these students that i have ventured to present a textbook
which provides a systematic and comprehensive coverage of the theory as well as
of the illustration of the applications thereof.
The present volumes grew out of more than a decade of classroom teaching
through lecture notes and assignments prepared for my students of BSc (General)
and BSc (honours). The schematic structure of the book is assigned to cover
the major topics of Physical Chemistry in six different volumes. Volume I
discusses the states of matter and ions in solutions. It comprises five chapters
on the gaseous state, physical properties of liquids, solid state, ionic equilibria
and conductance. Volume II describes the basic principles of thermodynamics
and chemical equilibrium in seven chapters, viz., introduction and mathematical
background, zeroth and first laws of thermodynamics, thermochemistry, second
law of thermodynamics, criteria for equilibrium and A and G functions, systems
of variable composition, and thermodynamics of chemical reactions. Volume III
seeks to present the applications of thermodynamics to the equilibria between
phases, colligative properties, phase rule, solutions, phase diagrams of one-,
two- and three-component systems, and electrochemical cells. Volume IV deals
with quantum chemistry, molecular spectroscopy and applications of molecular
symmetry. it focuses on atomic structure, chemical bonding, electrical and
magnetic properties, molecular spectroscopy and applications of molecular
symmetry. Volume V covers dynamics of chemical reactions, statistical and
irreversible thermodynamics, and macromolecules in six chapters, viz., adsorption,
chemical kinetics, photochemistry, statistical thermodynamics, macromolecules
and introduction to irreversible processes. Volume VI describes computational
aspects in physical chemistry in three chapters, viz., synopsis of commonly used
statements in BASiC language, list of programs, and projects.
The study of Physical Chemistry is incomplete if students confine themselves
to the ambit of theoretical discussions of the subject. They must grasp the practical
significance of the basic theory in all its ramifications and develop a clear
perspective to appreciate various problems and how they can be solved.
it is here that these volumes merit mention. Apart from having a lucid style
and simplicity of expression, each has a wealth of carefully selected examples and
solved illustrations. Further, three types of problems with different objectives in
view are listed at the end of each chapter: (1) Revisionary Problems, (2) Try Yourself
Problems, and (3) Numerical Problems. Under Revisionary Problems, only those
problems pertaining to the text are included which should afford an opportunity to
the students in self-evaluation. in Try Yourself Problems, the problems related to
the text but not highlighted therein are provided. Such problems will help students
extend their knowledge of the chapter to closely related problems. Finally, unsolved
Numerical Problems are pieced together for students to practice.
Though the volumes are written on the basis of the syllabi prescribed for
undergraduate courses of the University of Delhi, they will also prove useful to
students of other universities, since the content of physical chemistry remains the
same everywhere. in general, the Si units (Systeme International d’ unite’s), along
with some of the common non-Si units such as atm, mmhg, etc., have been used
in the books.
Salient Features
