Peter William Atkins FRSC (born 10 August 1940) is an English chemist and a Fellow of Lincoln College at the University of Oxford. He retired in 2007. He retired in 2007. He is a prolific writer of popular chemistry textbooks , including Physical Chemistry , Inorganic Chemistry , and Molecular Quantum Mechanics .
In physical chemistry, the McConnell equation gives the probability of an unpaired electron in an in aromatic radical compound (such as benzene radical anion) being on a particular atom. It relates this probability, known as the "spin density", to its proportional dependence on the hyperfine splitting constant .
In 1984, the Oxford physical chemist Peter Atkins, in a book The Second Law, written for laypersons, presented a nonmathematical interpretation of what he called the "infinitely incomprehensible entropy" in simple terms, describing the Second Law of thermodynamics as "energy tends to disperse".
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
Description: A classic general textbook for an undergraduate course in physical chemistry Importance: This book is not only a good introduction to the subject, it was very different from earlier texts and altered the way physical chemistry was taught. The first edition was very widely used where English is the language of instruction.
The Knudsen cell is used to measure the vapor pressures of a solid with very low vapor pressure. Such a solid forms a vapor at low pressure by sublimation.The vapor slowly effuses through the pinhole, and the loss of mass is proportional to the vapor pressure and can be used to determine this pressure.

Laurence Barron attended King Edward VI School, Southampton and then studied chemistry at the Northern Polytechnic, where he earned a First Class Honours Degree of London University in 1965. He studied at Lincoln College, Oxford , with Peter Atkins earning a D.Phil. in 1969, on the theory of nonlinear optical activity and birefringence , and ...
In thermodynamics, the phase rule is a general principle governing multi-component, multi-phase systems in thermodynamic equilibrium.For a system without chemical reactions, it relates the number of freely varying intensive properties (F) to the number of components (C), the number of phases (P), and number of ways of performing work on the system (N): [1] [2] [3]: 123–125
