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 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. The Antoine equation is an empirical fit to vapor pressure versus temperature data.

The Clausius-Clapeyron equation gives the relationship between P and T along the phase boundaries such as vapour to solid and vapour to liquid, whereas the  Mallen är daterad: 2019-10-07. Clausius–Clapeyron-ekvationen är en ekvation inom termodynamiken som beskriver sambandet mellan tryck och temperatur vid Clausius-Clapeyron equation and phase dia- grams. van der Waals tent heat is directly linked to the change of entropy between two phases (Eq. 12.8).

Clausius-Clapeyron equation An equation governing phase transitions of a substance, dp/dT = Δ H /(T Δ V), in which p is the pressure, T is the temperature at  

The Clausius-Clapeyron equation represents the relation between pressure and temperature in a two-phase equilibrium and the slope of dp/dT of the curve as well. We have several methods to derive this equation.

Learning Goals • Interpret the effect of changes in pressure on equilibrium transition temperatures. En termoquímica, la ecuación de Clausius-Clapeyron es una manera de caracterizar una transición de fase de primer orden que tiene lugar en un sistema monocomponente. En un diagrama P-T (presión-temperatura), la línea que separa ambos estados se conoce como curva de coexistencia. 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 . How to say clausius clapeyron equation in English?

Thus dQ = dW = pdV and where the equation of state gives p = nRT/V , hence. ∆S = ∫ dQ. T. = 195.198K≈ 195.2K. b: Clausius–Clapeyron dp. dT. = L. T∆v.

This doesn't look very useful, as we can't measure entropy directly.
