Hello everyone! I've encountered a small problem with one of our "special" assignments. Question: The normal boiling point for ethyl alcohol is 78.4 C, S for C2H5OH(g) is 282,7 J/mol*K. At what temperature is the vapor pressure of ethyl alcohol 357 mm Hg? Maybe I'm stupid, but I can't find a connection between the pressure and entropy. Or the phase transition. Original I thought it had something to do with Gibbs vs equilibrium, but now I'm even more confused. I'd love to do the problem myself but I'm in need of a hint/tip :) Thanks in advance.
