Boltzman distribution law

This equation describes an equilibrium distribution of the electroinactive ion in an electrostatic field. This is a typical situation to which one may apply the Boltzman distribution law, which states... [Pg.111]

The volumetric charge density is of interest in the study of ionic solutions, in which one can calculate the charge density around a specific ion. This is done by using the Poisson equation, based on electrostatic electric fields or by Boltzman distribution law of classical statistic mechanics. For the simpler case of dilute solutions this approach yields the expression p =... [Pg.84]

Fowler proposed a theory in 1931 which showed that the photoelectric current variation with light frequency could be accounted for by the effect of temperature on the number of electrons available for emission, in accordance with the distribution law of Sommerfeld s theory of metals. Sommerfeld s theory (1928) had resolved some of the problems surrounding the original models for electrons in metals. In classical Drude theory, a metal had been envisaged as a three-dimensional potential well (or box) containing a gas of freely mobile electrons. This adequately explained their high electrical and thermal conductivities. However, because experimentally it is found that metallic electrons do not show a gaslike heat capacity, the Boltzman distribution law is inappropriate. A Fermi-Dirac distribution function is required, consistent with the need that the electrons obey the Pauli exclusion principle, and this distribution function has the form... [Pg.46]

Other distribution functions such as the Maxwell-Boltzman distribution, (%2) distribution, etc. are used as well [99], A discrete law of bubble size distribution (Poisson distribution) is presented in [10]... [Pg.29]

No special equilibrium between activated complexes and reactants is assumed. It is supposed however, that within the space between qi and qi+Aqi, q2 and q2+Aq2, configurations (activated complexes) have impulses (motions) between pi and pi+Api,p2 and P2+AP2 respectively. These configurations are computed in accordance with Maxwell-Boltzmann distribution. Recall from the gas laws that an energy profile for molecules can be describe by the Maxwell-Boltzman distribution diagram (Figure 3.3). As the temperature goes up, the population of molecules with more energy also increases. [Pg.74]

At equilibrium, molecular energies will be distributed according to Boltzman s law and, finally, the general formulation which defines the factor f is given by Eq. (26) ... [Pg.20]

In previous publications, we have presented a formal treatment of the steady-state distribution of charges in terms of Boltzman s law with two allowed energy states. It... [Pg.97]

According to the law of distribution of molecular velocities (Glasstone and Lewis, 1960), molecules in two different phases, at equilibrium, are related in translation through the Boltzman equation, stated as... [Pg.54]
