Question
The thermodynamic properties of n-Hexane(1) and n-Heptane(2) gases can be expressed by the Peng
Robinson (PR) equation of state. Let's assume that the gas phase mixtures formed by these two
substances show ideal solution behavior up to 500 K and 10 bar pressure conditions. Molar enthalpy
(J/mol), entropy (J/molEK) and Gibbs energy (J/mol) properties of the gas mixture:
a) Determine for an equimolar mixture at 500 K and 10 bar.
b) Determine the mole fraction range 0–1 with an increment of x1 = 0.10 using a suitable computer
program (Python or Matlab). Present the results appropriately in a tabular form.
c) Determine the property changes of the mixtures in question due to mixing, with an increment of
x1 = 0.10 in the 0-1 mole fraction range. Present the results in tables and graphically, similar to
Figure 11.3 in the reference textbook (9th edition). Values in the range of 0-1 mole fraction are
expected to be realized according to the computer program (it may be a continuation of the program
in the other option). Solve for x1 = 0.40 by hand.
Some additional data/information:
• n-Hexane has an enthalpy property of 28.888 kJ/mol at 341.87 K and 1 bar conditions and an
entropy property of 84.606 J/molk.
• n-Heptane has an enthalpy property of 31.741 kJ/mol at 371.55 K and 1 bar conditions and an
entropy property of 85.532 J/molk.
• CP/R = A + BT + CT 2
