A method for determination of the second virial coefficient of a pure gas is based on the Clapeyron equation and measurements of the latent heat of vaporization (ΔHlv), the molar volume of saturated liquid (Vl), and the vapor pressure (Psat). Determine B in cm3/mol for methyl ethyl ketone at 75oC from the following data at this temperature:
ΔHlv=31,600 J/mol, Vl = 96.49 cm3/mol
ln(Psat)=48.157543-5622.7/T_ 4.70504 ln(T) T(K), Psat (kPa)
