Ethanol molar boiling-point

Here Vi is the molar volume of the solute / incm3/(mol) at its normal boiling point (for some values of Vu see Tables 2.9a and b), p the viscosity of solvent in pP, i//. an association parameter for solvent, and T the absolute temperature in K. Recommended values of the association parameters are 2.6 for water, 1.9 for methanol, 1.5 for ethanol, and l.Ofor benzene, ether, heptane, and other unassociated solvents. Equation (2.82) should be used only for dilute nondissociating solutions. 

The molar volume of ethanol at its boiling point can be estimated from the Rackett equation... 

Ethanol (CH3CH2OH) has a normal boiling point of 78.4°C and a molar enthalpy of vaporization of 38.74 kj mol Calculate the molar entropy of vaporization of ethanol and compare it with the prediction of Trouton s rule. 

Compare the normal boiling point of ethanol (78.2°C) with a molar mass of 46.07 g-moP to that of pentane (36.0°C) with a molar mass of 72.14 g-moP. ... 

The normal boiling point of ethanol, C2H5OH, is 78.3°C, and its molar heat of vaporization is 39.3 kj/mol (Appendix E). What would be the vapor pressure, in torr, of ethanol at 50.0°C ... 

The problem at hand is to calculate the boiling point of a water-ethanol mixture at 5%, 10%, 25%, and 35% molar in ethanol at the ambient pressure of 760 mmHg. 

Finally, we present an example to compute the boiling point of the mixture of water and ethanol at 25% molar. From the literature, we find the coefficients from the Antoine correlation for water to be A = 18.3036 B = 3816.44 C = 227.02 [1]. The boiling point of any ideal mixture is calculated as...
