Entropies and Enthalpies for Self-Diffusion in Potassium Bromide

Abstract

The measured electrical conductivity of pure KBr is analyzed into anion and cation components in two ways, and the results compared with those obtained by direct diffusion measurements. It is found that analysis of the conductivity using only the intrinsic region is unreliable and leads to an overestimate of the anion and an underestimate of the cation activation entropy and enthalpy.
