Clayperon formula
WebThe meaning of CLAPEYRON EQUATION is an equation relating to change of phase in a pure substance (as vaporization of a liquid) that gives the rate of change with temperature of the pressure at equilibrium between the phases in terms of the heat of transition and the volumes of the phases before and after the transition. WebClapeyron equation and related the equilibrium vapor pressure to the temperature of the …

WebThe 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 . Hence, a plot of lnP versus 1/T yields a straight line the slope of which is equal to –(h fg /R). Kirchoff Equation WebThis form of the Clausius-Clapeyron equation has been used to measure the enthalpy of vaporization of a liquid from plots of the natural log of its vapor pressure versus temperature. For our purposes, it would be more useful to take advantage of logarithmic mathematics to write this equation as follows. Because the molar enthalpy of ...
Web7.11 When the der Waals equation in written in terms of the reduced variables p r, V r and T r, the critical pressure, temperature and volume are equal to one. Consider small deviations from the critical point, p r=1+ δp and V r=1+ δV on the critical isotherm. Show that δV is proportional to ( δp)1/3. This corresponds to the classical ... WebJun 1, 2024 · Abstract It is necessary to calculate the saturation vapor pressure of water and of ice for some purposes in many disciplines.

The Clausius–Clapeyron equation: 509 applies to vaporization of liquids where vapor follows ideal gas law and liquid volume is neglected as being much smaller than vapor volume V. It is often used to calculate vapor pressure of a liquid.
