Homework Statement
The vapour pressure of a certain liquid is given by the equation:
[tex]\log_{10}P=3.54595-\frac{313.7}{T}+1.40655\log_{10}T[/tex]
where ##P## is the vapour pressure in mm and T is temperature in kelvin. Determine the molar latent heat of vapourisation as a function of temperature. Calculate its value at 80 K.
Homework Equations
The Attempt at a Solution
I am really clueless about where to start. The liquid vapourises at a temperature when its vapour pressure is equal to the atmospheric pressure. I can calculate the boiling point from here but I don't think that would help here as I need molar latent heat of vapourisation as a function of temperature.
Any help is appreciated. Thanks!
