Due to this formulation, given one point on a coexistence line, we can discover other points on the line and the slope of the line. It is not thermodynamically exact because it contains two approximations and only applies when one of the phases in the transition is a gas. It states the temperature of the system, the ideal gas constant, and the molar enthalpy of vaporization of the liquid determine the rate at which the natural logarithm of the vapor pressure of a liquid changes with temperature. FTP, identify this equation named for its two discoverers.
