Of the following binary liquid/vapor systems, which can be approximately modeled by Raoult’s law? For those that cannot, why not? Table B.1 (App. B) may be useful.
(a) Benzene/toluene at 1(atm).
(b) n-Hexane/n-heptane at 25 bar.
(c) Hydrogen/propane at 200 K.
(d) Iso-octane/n-octane at 100°C.
(e) Water/n-decane at 1 bar.
