3.) Calculate the molar enthalpy of vaporization AHV₁ of nitrogen at the given temperature

and the corresponding saturation vapor pressure P₁. Use the Antoine equation as

a means to get vapor pressures at 0.1K above and below the given temperature

T = -155.2 °C. Assume a linear slope of the vapor pressure curve (6.0 Points)

Now you are interested in the phase equilibrium of a mixture of another component (index 1)

and oxygen (index 2) at p = 10 bar and the given temperature T = -155.2 °C. The Margules

parameters for the mixture are A₁2 = 0.8 and A₂1 = 1.4.
