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