This book is the second of the 7-volume series, which provides an extensive coverage of Physical Chemistry. Sixth edition of Volume 2 exhaustively describes the Basic Principles of Thermodynamics and Chemical Equilibrium. Latest IUPAC recommendations and SI units have been used throughout the book. New additions to the sixth edition include: (i) expressions relating inversion temperature and Boyle Temperature, and (ii) the quantitative variations of reduced inversion temperature with reduced pressure of gases based on van der Waals Berthelot, Dieterici and Redlich-Kwong equations of state.\n\nSalient Features:\n• Expanded coverage of derivations on expressions relating Boyle temperature and inversion temperature for all states of equations \n• Detailed discussion on expressions relating Reduced Inversion Temperature and Reduced Pressure for all states of equations\n• Extensive chapter-end numerical including Revisionary Problems, Try Yourself Problems and Numerical Problems
