The Wikipedia page on the heat of vaporization has a nice graph showing the heat of vaporization going to zero at the critical points of various substances. Is there a known form for the heat of vaporization as a function of temperature near the critical point? I imagine it is probably a power law with some exponent, and while there are lists of critical exponents I can't figure out which critical exponent it would be. I could fit the data to a power law by hand but I wonder if there is a more definitive source.
