When benzene is used to dry 95% (by weight) ethanol, two azeotropes are involved: a ternary azeotrope (bp 65) containing 74% by weight benzene, 18.5% ethanol, and 7.5% water, and a binary azeotrope (bp 68) consisting of 68% benzene and 32% ethanol. assuming a safety factor of 10% excess, calculate the amount of benzene needed to dry 1 kg of 95% ethanol. how much absolute ethanol would be obtained?

Routon's rule trouton's rule states that the entropy of vaporization is almost the same value, about 87-88 j/(k⋅mol), for various types of liquids. this implies that approximately the same amount of disorder is generated in the passage of one mole of a substance from liquid to gas, when comparisons are made at the normal boiling point. part b liquid boiling point (k) enthalpy of vaporization (kj/mol) benzene 353.1 30.72 toluene 383.6 33.18 nonane 423.8 37.18 chloroform 334.2 29.24 ethanol 351.3 38.56 water 373 40.65 predict which of the following compounds follow trouton's rule. check all that apply. view available hint(s) hint 1. calculate the entropy of vaporization for a sample liquid check all that apply. ethanol water nonane benzene chloroform toluene
