Perhaps my understanding is too limited to help, but I find the question
interesting. May I correctly restate the question as:
"Is the enthalpy of hexane adsorption greater for an air/H2O(l) interface
or for an air/H2O(s) interface?"
Please let me know so I can think about it while I drive home...
Thanks -
