For a binary system of components 1 and 2, I went to the lab and from experimental L-V phase equilibrium data I determined the following expressions for the activity coefficients of components 1 and 2:

ln( 1)=(x2)^2[+2()1 +3(1)^2]

ln( 2)=(x1)^2[+2()2 +3(x2)^2]

Where the parameters A, B and D may depend on temperature.

Find an expression for ln(1^H), where 1^H is the activity coefficient of component 1 but now using the

Henrys law reference state.
