2.) Calculate the coefficients a1, 02, a12, a, b and finally the pressure p of the mixture with

the Peng-Robinson equation. Use the nitrogen mole fraction y₁ 0.4 and the molar

m³

kmol

=

volume V = 7.544

(13.0 Points)

You want to look into the phase change data of nitrogen. Use the Clausius-Clapeyron

equation. Ideal gas behavior as well as a constant molar enthalpy of vaporization can be

assumed, and the molar volume of the liquid phase is small compared to that of the gas

phase.
