The Free Energy and Entropy of Nitrosyl Chloride

摘要

Using the harmonic oscillator rigid rotator approximation to the partition function of nitrosyl chloride, the values of the free energy function, (F0—E00)/T, and the entropy,S0, have been calculated for the ideal gas from 298.1°K to 1000°K at fifty degree intervals. By comparison with the equilibrium data for the dissociation of nitrosyl chloride, &Dgr;E00is found to be 15,510±53 cal. It is found necessary to assume an electronic weight of four for the ground state. Although the calculated equilibrium constants agree fairly well with experiment, a definite trend in the deviations cannot be satisfactorily explained.
