Question:

The excess Gibbs energies for liquid argon–methane mixtures have been measured at several temperatures. The results are

yex Ge *Ar(1 - Ar){A - B(1 - 2 Ar)} where numerical values for the parameters are RT T (K) A 109.0 0.3024

Compute the following:

a. The activity coefficients of argon and methane at 112.0 K and x_Ar = 0.5

b. The molar isothermal enthalpy change on producing an x_Ar = 0.5 mixture from its pure components at 112.0 K

c. The molar isothermal entropy change on producing an x_Ar= 0.5 mixture from its pure components at 112.0 K
