Physical chemistry is difficult because of thermodynamics and kinetics. Physical chemistry itself is to solve chemical problems by physical and mathematical methods. Difficult to physics, difficult to mathematics. Nantah is the best physical chemistry textbook recognized in China, followed by some good books from other schools, such as the physical chemistry book by Academician Hu Ying, such as Yin Yongjia's A Brief Course of Physical Chemistry. Of course, the reference book is their supporting reference book, which is a review guide for physical chemistry postgraduate entrance examination. This book is also a very classic reference book of physical chemistry. Whether studying or taking the postgraduate entrance examination, the value of this book is considerable, which is very good for understanding the concepts in physical chemistry. Generally speaking, under the guidance of Physical Chemistry Book written by Nanda Fu, we can familiarize ourselves with concepts by thinking about problems after class in each chapter, and learn to understand them together with the review guidance of physical chemistry. Physical chemistry will certainly be greatly improved. Whether a good teacher or a poor teacher, self-study is the most important link. Physical chemistry is difficult to learn without its own understanding. There are many exercises in the physical chemistry book of Tianjin University, but there are many mistakes in the book. When reading this book, please distinguish the mistakes so as not to be misled.
