Aspects of Physical Chemistry

This whole area of spectroscopy touches on many different topics and can only be approached confidently with a reasonable working knowledge of basic NMR, stereochemistry and certain aspects of physical chemistry. 

Computational chemistry offers many advantages to teachers of physical chemistry. It can help students learn the material and develop critical thinking skills. As noted before, most students will probably use some sort of computational method in their chemistry careers, so it provides students with important experience. Furthermore, computational chemistry is much more accessible to undergraduate students than it was a decade ago. Desktop computers now have sufficient resources to calculate the properties of illustrative and interesting chemical systems. Computational software is also becoming more affordable. Students can now use computers to help them visualize and understand many aspects of physical chemistry. However, physical chemistry is also an experimental science, and computational models are still judged against experimental results. 

The primary objective of this book is to bridge the gap between today s typical physical chemistry course and the literature of colloid and surface chemistry. The reader is assumed to have completed a course in physical chemistry, but no prior knowledge of the topics under consideration is assumed. The book is, therefore, introductory as far as the topic subjects are concerned, although familiarity with numerous other aspects of physical chemistry is required background. 

We clearly cannot cover all aspects of physical chemistry here. However, we attempt to provide enough theoretical background for the reader with training in mechanical or chemical eningeering to understand what is needed to develop and analyze chemically reacting flow models. This includes understanding the chemistry input parameters that someone else has determined and, more important, being able to estimate parameters that are needed to do a simulation but simply do not exist in the literature. 

The p factor could also be a consequence of the physically naive hard sphere model used. This model requires that there be no intermolecular interactions either at close distances or at a distance. This has been shown not to be the case, with evidence coming from many aspects of physical chemistry. Also, vibrations and rotations do affect reaction, as is shown by experiments with molecular beams. 

When the plot of oge(k/T) versus 1/7 is drawn, there is a very long extrapolation to zero for 1/7. To carry out this extrapolation would require a ridiculous amount of graph paper, or a ridiculous bunching together of points on ordinary graph paper. Graphical extrapolation is impossible, and the value of the intercept must be found by calculation. This can happen in various aspects of physical chemistry, and very often occurs in plots vs 1/7. 

If one considers theory to be at the opposite side of experiment, then Barriol was not a theoretical chemist. Was he, in these conditions, a physical chemist It is within the area of physical chemistry that our laboratory took the occasion to perform the most significant advances said Barriol, modestly. As a matter of fact, most papers were published in the Journal de Chimie Physique and the notes in the Academie des Sciences were mostly read in the physical chemistry section. Like Bauer, Barriol was interested in the theoretical aspects of physical chemistry. But, more generally, he can be considered as a kind of generalist, working at the center of the chemist s preoccupations - the structure of molecules and the nature of their interactions -who dominated general questions of fundamental chemistry, who could go ahead, rather far, in specialized directions of high interest, who was able to distribute problems to more specialized disciplines and, vice versa, to think about the responses.

The primary aim of this book is to help in remedying this situation. It can be used as the basis of a course for food science majors at a not-too-early stage in the curriculum (some universities may prefer a graduate course). Hence it is written as a textbook. A second aim is its use as a reference book, since basic aspects of physical chemistry are not always taken into account in food research or process development. Therefore, I have tried to cover all subjects of importance that are not treated in most courses in food chemistry or food processing/engineering. 

SCOPE OF THE TEXT The main aspects of physical chemistry-structure, thermodynamics, electrochemistry, and kinetics—have been dealt with, but I have deemphasized or omitted some topics which do not apply very much outside chemistry. This has allowed me to cover in greater depth certain topics such as transport properties in macromolecular systems, membrane equilibria, action potentials, and the use of isotopes in the study of reaction mechanisms. All of these are of great importance in biology as well as in chemistry. 

It is important to stress again that what we have done so far is to draw together several aspects of physical chemistry and show how they are relevant to the study of colloids.
