A study of the Clausius equation of state.

Abstract

The purpose of this work is to present an approach and its limitations as applied to the Clausius equation of state to calculate the volume and the heat of mixing. The investigation was begun to continue the research into volume and heat of mixing, specifically through an evaluation of the latest modification of the Clausius equation of state, simply by considering the three parameters as temperature dependent. The results of the evaluation indicate that the proposed approach is good for predicting volumes of mixing but not entirely adequate for predicting heats of mixing. Thus, an alternative approach has been investigated by considering two of the parameters as temperature dependent which appears more adequate and versatile for predicting these thermodynamic properties.
