In this book, the chapters "Intermolecular forces - additive properties", "Thermochemistry", "Chemical kinetics", and "Chemical equilibrium" of Chemistry B' High School, Group of Orientation of Positive Studies and Health Studies are presented in detail. The structure of the textbook is faithfully followed.

It includes:
- Analytical theory for a complete understanding of the subject matter.
- Theory questions with the correct answer, covering the "difficult points" of the 2nd topic of the National Examinations.
- Multiple-choice questions with justification for the theory, according to the 1st and 2nd topic of the National Examinations, for the student's answer.
- Basic exercises exemplarily solved according to the corresponding methodology.
- Exercises and problems for solution, the number and diversity of which ensure the student's proper preparation.
- Tests after each chapter section, according to the topics of the National Examinations.
- Combined topics in the examined sections.
- Appendix with the answers to all the topics.

The great advantage of this work is that it exhausts the material of the 2020-2021 school year required by the analytical program and therefore is within the philosophy of the national examinations without, however, expanding into details that tire the student and the teacher and which actually concern another educational level.
