Several of my chemical colleagues have suggested that a new edition of M. and S. should now deal also with the chief branches of modern spectroscopy. This would be an aim both excellent and impracticable. Students have their own monographs on spectroscopy and their own teachers, whose exposition should clarify the branches of this subject more rapidly and easily than the printed text. An attempt to deal adequately with spectroscopy in this olume would greatly increase its size and probably fail in purpose—the fate of several books whose authors have attempted this ambitious programme. 

An e.xplosion is an event in wliich energy is released over a time sufficiently short and in a I olume sufficiently small to permit tlie generation of a pressure wa e of finite amplitude traveling away from tlie source. 

The total fixed volume of a mixture of gases and vapors at a giv en condition is the same as the olume of any one component (gas laws), and its pressure is composed of the sum of the individual partial pressures of each component.

Prof. Jerzy Sobkowski starts off this 31st olume of Modern Aspects of Electrochemistry with a far-ranging discussion of experimental results from the past 10 years of interfacial studies. It forms a good background for the two succeeding chapters.

Equation (6) indicates that secondary nucleation is significantly affected by the crystal surface area A (m2/l). The nucleation process is usually viewed as a process where copious amounts of fines are produced, resulting in a corresponding increase in the specific crystal surface area (m2/g) and crystal surface areaA olume of the crystallizer content (m /l). Results obtained in this study concur with this nucleation view. However, Brown (9) reported that nucleation can be suppressed at high crystal surface areas ( 20 m2/l). Brown s observation was not evident in this study though the seed density of 200 g/litre used in this study had a surface area of 25 m2/l. The lower dependence of second nucleation on supersaturation or concentration driving force, AC, in comparison to crystal surface area. A, is obvious from equation (6). 

Further, we want to be able to work problems with numerical solutions. This will require simplifying assumptions wherever possible so that the equations we need to solve are not too messy. This wiU require that fluids are at constant density so that we can use concentrations in molesA olume. This is a good approximation for hquid solutions but not for gases, where a reaction produces a changing number of moles, and temperatures and... 

Note that, if we measure the rate per weight of catalyst, we do not need to worry about the packing of the catalyst in the reactor (determined by s) but just the density of the catalyst Pc in weightA olume. 

We can also use chemical kinetics to attempt to model populations of living systems such as single-celled organisms or plant, animal, and human populations. We describe the density of individuals (species A) as Ca, which might be in individualsA olume in a three-dimensional... 

We included the term r = 0 to indicate that there is no reaction in the gas phase. The mass transfer rates obviously have opposite signs, and we have to multiply the mass transfer flux by [areaA olume], where the volume is that occupied by that phase. Note that the mass transfer term after dividing out becomes proportional to R. Since the reactor volume is proportional to R while the surface area for mass transfer is proportional to R, the falling film column obviously becomes less efficient for larger reactor sizes. This is a fundamental problem with the falling film reactor in that small tubes give high mass transfer rates but low total production of product. 

The Russian criticism of the theory of resonance seems to be based largely upon the fact that the contributing resonance structures do not have real existence.44 Essentially the same point is made in HiickeFs book Structural Chemistry of Inorganic Compounds Kh in the last paragraph of V.olume I, in a note of criticism of the theory of resonance supplied by the translator of the English edition, L. H. Long, the complaint is expressed in the following words ...
