Answer the following statement(s) true (T) or false (F)
A. A mixture of ethanol + ethane will exhibit cross-association interactions, where a hydrogen-atom on the ethane will hydrogen-bond with the oxygen atom on the ethanol B. If a mixture forms an azeotrope, it will show an azeotrope at all temperatures where vapor-liquid phase equilibrium can exist for the system. C. In retrograde condensation, as the system pressure is decreased, more of the liquid phase (relative to the vapor phase) will form. D. The lever rule is generally more accurate than performing material balance calculations to determine the amounts of the phases in equilibrium since you are able to measure the distances using a ruler. E. None of the above are true.
