Example 2.18: Benzene (A) is in equilibrium with
2,3,4-trimethylpentane (B). The
following data apply:
pT
= 201.74 mmHg, T = 55 °C,
PA
= 327.05 mm Hg, PB
= 178.08 mm Hg,
xA
= 0.0819, yA
= 0.1869
Calculate the activity coefficient of A and B and excess
Gibbs energy.
Solution
$
Activity coefficient of benzene, γA (Equation 2.59)
|
|
$
Activity coefficient of
2,3,4-trimethylpentane (Equation 2.59)
|
|
$
Excess free energy, Gex (Equation 2.58)
