Selected Values of Chemical Thermodynamic Properties

Prepared by David R. Lide.
Introduction
The theoretical framework of thermodynamics was well established by the time NBS was founded, and certain important applications, such as improving the efficiency of steam engines, had been demonstrated. However, the broad application of hermodynamics to the design and control of industrial processes had to await the accumulation and organization of a large amount of experimental data, as well as theoretical contributions from quantum mechanics and statistical mechanics. The appearance of Selected Values of Chemical Thermodynamic Properties [1] in 1952 marked a significant milestone in this process. This book represented the culmination of 20 years of work
by Frederick D. Rossini and coworkers in evaluating and systematizing the data that had appeared in the world literature on thermochemistry.

Thermodynamic Properties of Liquid Alkali Metals Using a Charged Hard, Sphere Reference System

this journal now available and free download able at Chinese journal of physics, written by P. B. Thakor, V. N. Patel, P. N. Gajjar, and A. R. Jani from Department of Physics, Sardar Patel University, Gujarat, India, introduce The Gibbs-Bogoliubov (GB) inequality, the experiment results : Structure of liquid metals,Thermodynamic properties,Pseudopotential method.

abstraction

The Gibbs-Bogoliubov (GB) inequality is used to evaluate the Helmholtz free energy of
liquid alkali metals as a function of temperature. The structural contribution to the Helmholtz free energy is investigated by adopting a charged hard sphere fluid model. A well established single parametric local pseudopotential is applied to describe the electron-ion interaction along with five different local field correction functions viz; Hartree, Taylor, Ichimaru and Utsumi, Farid et al., and Sarkar et al., 6.2% to 51.15% of the influence on the Helmholtz free energy is concluded to be due to these local field correction functions with respect to the static Hartree dielectric function. Very good agreement with experimental results is achieved.
