Clausius-Clapeyron equation and enthalpy

  1. Apr 9, 2010 #1
    1. The problem statement, all variables and given/known data
    Use the Clausius-Clapeyron equation and [tex]\Delta[/tex]Hsub = [tex]\Delta[/tex]Hfus +[tex]\Delta[/tex]Hvap at the triple point to show that the slope of solid-gas P-T coexistence curve is greater than the slope of the liquid-gas coexistence curve.


    2. Relevant equations
    Clausius-Clapeyron: 1/P (dP/dT) = [tex]\Delta[/tex]h/RT^2


    3. The attempt at a solution
    How does this all relate to the question? I dont understand

    If you do not understand the relationship to the question, it suggests that you either do not understand the meaning of the symbols in the question or the meaning of the symbols in the C-C Eqn.

    A good starting point is writing out what the C-C Eqn is saying, in words.
