Q10 Raoult's Law

20 Points

You know the infinite dilution activity coefficients in a mixture are as follows: = 1.68 and

1.25. What would be the most reasonable values for the parameters of this system

according to the 2-parameter Margules equation?

O A12= 1.251; A21 = 1.682

O A12= 1.682; A21 = 1.251

O A12 = 0.519; A21 = 0.223

O A12 = 5.372; A21 = 3.491

O A12 = 1.473; A21 = 1.473
