Question:

The following vapor-liquid equilibrium data are available for methyl ethyl ketone: 

Heat of vaporization at 75°C: 31 602 J/mol Molar volume of saturated liquid at 75°C: 9.65×10−2 m3 /kmol

In Pvap 43.552 - 5622.7 T 4.705 04 In T

where P  is the vapor pressure in bar and T is in K. Assuming the saturated vapor obeys the volume explicit form of the virial equation,

V = RT P + B

Calculate the second virial coefficient, B, for methyl ethyl ketone at 75°C.
