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 75⁰C 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)
