Francis' Elementary Differential Equations with Applications: Part 1

A derivation of the Clausius-Clapeyron equation can be found in Section 4.5 of Atkins, Physical Chemistry 9th Ed.) En chimie physique, et plus particulièrement en thermodynamique, la formule de Clausius-Clapeyron (ou relation de Clausius-Clapeyron, équation de Clausius-Clapeyron) est une forme simplifiée de la formule de Clapeyron permettant son intégration dans le cas d'un équilibre liquide-vapeur d'un corps pur. Clausius-Clapeyron Equation It is possible to characterize the phase-equilibrium line in terms of a differential equation. Referring to Figure 9.1, consider a point, such as , that lies on the phase-equilibrium line, and corresponds to the temperature and the pressure .

For example, as the temperature of the atmosphere increases its water holding capacity also increases according to the Clausius-Clapeyron relationship. The Clausius–Clapeyron equation determines the vapor pressure of a liquid as a function of temperature (in degrees K). In differential form, the CC equation can be written , where is the standard molar enthalpy of vaporization. If the enthalpy of vaporization is assumed constant over a temperature range, the equation can be integrated to give The Clapeyron equation becomes: or . which is known as the Clausius-Clapeyron equation. Assume that is constant over a small temperature range, the above equation can be integrated to get, or +constant .

Clausius-Clapeyron equation, which gives the slope of the vapor pressure curve. We could then measure the vapor pressure curve for various substances and compare the measured slope to the Clausius-Clapeyron equation. This can then be viewed as an 1) Let us use the Clausius-Clapeyron Equation: ln (x / 1.00) = (30800 / 8.31447) (1/353.25 minus 1/298.65) Comment: I used the form of the equation shown in this image: I assigned the unknown value to be associated with P 2.

We could then measure the vapor pressure curve for various substances and compare the measured slope to the Clausius-Clapeyron equation. This can then be viewed as an What is Meant by the Clausius Clapeyron Equation? Clausius Clapeyron equation is used to determine the vapour pressure at any other temperature if the vapour pressure and the enthalpy of vaporization at some temperature are known. We know that the vapourization curve for most of the liquids has the same curve.
