Quasi-static Method for the Determination of the Heat and Entropy of Vaporization of the Solvent Mixture
Abstract:
The principles of the method of boiling point elevation with which the heat and entropy of vaporization of solvent mixture are determined are discussed in detail. Quasistatic method is used to determine the normal boiling points for different concentrations of binary systems of ethanol-acetone, benzene-carbon tetrachloride and benzene-toluene. According to the data of boiling point, the differential heats and the entropies of vaporization are calculated. The obtained results show that when the deviations of the binary solvent mixture conforms to Trouton’s rule.
