For a gas obeying van der Waals equation, the van der Waals molar intermolecular attraction (U_ lnter , m ) is given by U_ inter , m =-a / V_ m , where, a is a positive constant and V_ m is the molar volume. The plot of U_ intec, m versus V_ m for diethyl ether ( ( C ₂ H ₅ )₂ O ) is shown below. Given that V_ m is 110 ~cm ^3 / mol at 35^ C and 1 atm, the U_ m and H_ m of vaporization of diethyl ether at 35^ C respect
