d ln p/ dT = ΔvapH /RT2
Like the Clapeyron equation, the Clausius–Clapeyron
equation is important for understanding the appearance of phase diagrams, particularly
the location and shape of the liquid–vapour and solid–vapour phase boundaries.
It lets us predict how the vapour pressure varies with temperature and how the boiling
temperature varies with pressure. For instance, if we also assume that the enthalpy of
vaporization is independent of temperature
