Easiest Way to Solve Physical Chemistry Problems


Physical chemistry is the study of the underlying physical principles that rule the properties and behavior of chemical systems.

A chemical system can be studied from either a macroscopic or microscopic viewpoint. The microscopic viewpoint is laid on the concept of molecules. The macroscopic viewpoint studies large-scale properties of matter without explicit use of the molecule concept. The first half of this book uses mainly a macroscopic viewpoint; the second half uses mainly a microscopic viewpoint.


We can categorize physical chemistry into four areas: thermodynamics, quantum chemistry, statistical mechanics, and kinetics. Thermodynamics is a macro- scopic science that studies the interrelationships of the various equilibrium properties of a system and the changes in equilibrium properties in processes.  Molecules and the electrons and nuclei that create them do not obey classical mechanics. Instead, their motions are governed by the laws of quantum mechanics. Application of quantum mechanics to atomic structure, molecular bond- ing, and spectroscopy gives us quantum chemistry.

The macroscopic science of thermodynamics is a consequence of what is hap- pening at a molecular (microscopic) level. The molecular and macroscopic levels are related to everyone by the branch of science called statistical mechanics. Statistical mechanics gives insight into why the laws of thermodynamics hold and allows calculation of macroscopic thermodynamic properties from molecular properties.

Kinetics is the study of rate processes such as diffusion, chemical reactions and the flow of charge in an electrochemical cell. The theory of rate processes is not as well created as the theories of thermodynamics, statistical mechanics and quantum mechanics. Kinetics uses related parts of thermodynamics, statistical mechanics and quantum chemistry.

Improvement and excellence in Higher Education

A lot is varying in higher education. Most essentially, apprentice themselves are changing. Subsequent to long decades of ruling out, college access has extended opportunities for minority students, first-generation students and low-income students. In this year students are more probable to attend community college than any other postsecondary alternative and more probable to be older and living away from campus and may be joining part-time while balancing work as well as family. The symbolic picture of an 18-year-old high school graduate walking across a blossoming campus toward her dorm room no longer reflects the actuality of today’s college student. Institutions of higher education are act in response to these changes, partially by making course delivery more pliable. Technology has prepared this even further possible, introducing teaching as well as learning that is less forced by time and place. Technology is as well making new kinds of embedded assessment and adaptive curriculu...

Contribution of Quantitative Techniques to Managerial Economics

 Contribution of Quantitative Techniques to Managerial Economics   Mathematical Economics and Econometrics are utilised to construct and estimate decision models useful in determining the optimal behaviour of a firm. The former helps to express economic theory in the form of equations while the latter applies statistical techniques and real world data to economic problems. Like, regression is applied for forecasting and probability theory is used in risk analysis. In addition to this, economists use various optimisation techniques, such as linear programming, in the study of behaviour of a firm. They have also found it most efficient to express their models of behaviour of firms and consumers in terms of the symbols and logic of calculus. Thus, Managerial Economics deals with the economic principles and concepts, which constitute 'Theory of the Firm'. The subject is a synthesis of economic theory and quantitative techniques to solve managerial decision problems. It is rn...
