Statistical thermodynamics performs an important linking position among quantum idea and chemical thermodynamics, but scholars frequently locate the topic unpalatable.

during this up to date model of a well-liked textual content, the authors triumph over this by way of emphasising the strategies concerned, specifically demystifying the partition functionality. they don't get slowed down within the mathematical niceties which are crucial for a profound examine of the topic yet which could confuse the newbie. powerful emphasis is put on the actual foundation of statistical thermodynamics and the kinfolk with test. After a transparent exposition of the distribution legislation, partition capabilities, warmth capacities, chemical equilibria and kinetics, the topic is extra illuminated by means of a dialogue of low-temperature phenomena and spectroscopy.

The assurance is introduced correct brand new with a bankruptcy on desktop simulation and a last part which levels past the slender limits frequently linked to scholar texts to stress the typical dependence of macroscopic behaviour at the homes of constituent atoms and molecules.

considering the fact that first released in 1974 as 'Entropy and effort Levels', the ebook has been highly regarded with scholars. This revised and up-to-date model will doubtless serve an identical wishes.

Example text

For example, take the case of putting 2 particles (n, = 2) in a four-fold degenerate set of levels (p, = 4). If we leave the first level empty, we are then putting 2 particles in 3 levels which the previous entry for n, = 2 shows can be done in 3 ways. If we put a particle in the first level we are left with the task of putting one particle in a choice of three levels (or ‘boxes’) which can also be done in 3 ways. The total number of ways is therefore 3+3 = 6. The general conclusion is that the number of ways in which n, indistinguishable particles can be distributed in p , levels, each of which can accommodate one particle, is wni,p; = Pi !

This consideration reduces the number of ways of realizing one particular state, and so W and S are also reduced, but leaves the relative populations of the levels unaffected. Separation of the Partition Function If we remember that, physically, the partition function tells us how molecules are distributed among the available energy levels and that there are several sorts of energy, we can separate various contributions to the partition function. We can often express the total energy of a molecule as the sum of the translational, rotational, vibrational and electronic energy terms E = Etrans f E r o t f E v i b f Eel .

This is done in detail in Appendix 4. The Dissociation Energy of Fluorine The above method has been used in reverse in the case of fluorine where a measured equilibrium constant was used to determine A H e ( = D ) the dissociation energy of the molecule. This calculation is also a typical example of the advantage there may be in using the third law rather than the second law for determinations of enthalpy changes. For Fz dissociation the following equilibrium was considered This dissociation takes place to an appreciable degree only at elevated temperatures.
