The Clapeyron-Clausius equation is a differential equation giving the interdependence of the pressure and temperature along the phase equilibrium curve of a pure substance. This equation was suggested by B. Clapeyron in 1834 and improved by R. Clausius in 1850. Se hela listan på e-education.psu.edu The Clausius-Clapeyron equation is for vapor-liquid or vapor-solid equilibrium and assumes the gas phase is ideal. The Clapeyron equation can be applied to two phases in equilibrium: vapor-liquid, vapor-solid, solid-liquid.

And here one way will be showed. * α and β in the following derivation stand for phase A and phase B during the phase transition The Clausius-Clapeyron equation may be applied to pure substances and to solutions and the separate components of solutions. In the latter cases, the Clausius-Clapeyron equation relates the partial pressure of unsaturated vapor of a given component to its partial heat of vaporization. Clausius-Clapeyron-ekvationen relaterar en lösnings ångtryck vid olika temperaturer till förångningsvärmen.

The vapor pressure of water, for example, increases significantly more rapidly than the temperature of the system. This behavior can be explained with the Clausius-Clapeyron equation. Equation 23.4.6 is known as 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. Clausius-Clapeyron Equation The Clausius-Clapeyron equation approximately relates a substance’s vapor pressure and its temperature. (The exact relationship is called the Clapeyron equation. A derivation of the Clausius-Clapeyron equation can be found in Section 4.5 of Atkins, Physical Chemistry 9th Ed.) The Clausius-Clapeyron Equation The relationship between the temperature of a liquid and its vapor pressure is not a straight line.

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 . The condition implies that The Clausius-Clapeyron equation relates the latent heat (heat of transformation) of vaporization or condensation to the rate of change of vapour pressure with temperature.
