ABOUT THE BOOK:
Problems on physical chemistry appear really as problems to most of the students of physical chemistry. One of the reasons for this may be an inadequate number of classes held (in most of the colleges) in comparison to the vast syllabus prescribed. Very often a teacher in physical chemistry does not find sufficient time to complete his theoretical course and problems remain almost untouched in the classroom. Considering this, I thought of writing a book on problems alone so that a student himself can solve his own problem. Very few books are available on this topic and perhaps none of them is totally made for chemistry honours students of our universities.
The present book having sixteen chapters completely covers the chemistry honours syllabus of all Indian Universities. Each chapter can be divided into two halves. The first half consists of typical problems of various types picked up from different standard textbooks. In picking up such problems I have consulted textbooks of Atkins; Moore; Castellan; Maroon and Prutton; Barrow; Adamson; Kapoor and also of P. C. Rakshit. The second half of each chapter deals with university question papers. Problems of question papers of the last twenty years of Calcutta University and the last ten years of Burdwan University have been solved. Almost all problems are solved. Those, unsolved are provided with hints. Most of the problems are in traditional units and few are in S.I. Units. However, considering the growing importance of S.I. Unit I have discussed it in detail in the introduction, where interconversion of two systems of units is dealt with. Few problems solved in both systems of units are included in the introduction. I think, if a student goes through the introductory discussion with attention, he will not see any problem from either traditional or S.I. system of units.
