CEOS - Alpha functions requirement

  1. Apr 22, 2017 #1
    I seem to have forgotten where I have seen these particular rules; I need them for my research. I think I saw them in a book somewhere... but that was around 4 years ago.

    Does anyone know where can I find the rules stipulated by statistical mechanics/thermodynamics on the alpha function α(TR) of the cubic equations of state?

    As far as I remember, there were three rules:
    • α(TR) = 1 when TR = 1
    • α(TR) approaches 0 when TR approaches infinity
    • α(TR) approaches infinity (???) when TR approaches 0
    Please do correct me if I am incorrect; and kindly point me to such resource if you guys happen to know. Thanks!
