4. Integration of the Clapeyron equation

Clapeyron's differential equation is perfectly rigorous, but cannot be integrated without approximation, since enthalpy and vaporization compressibility factor are complicated functions of temperature.

As shown in figure 2 , these two quantities are decreasing...
