?The following expressions have been reported for the activity coefficients of species 1
Chapter 13, Problem 13.55(choose chapter or problem)
The following expressions have been reported for the activity coefficients of species 1 and 2 in a binary liquid mixture at given T and P: \(\gamma_{1}=x_{2}^{2}\left(0.273+0.096 x_{1}\right) \quad \ln \gamma_{2}=x_{1}^{2}\left(0.273-0.096 x_{2}\right)\)
(a) Determine the implied expression for \(G^{E} / R T\).
(b) Generate expressions for ln \(\gamma_{1} \text { and } \ln \gamma\) from the result of (a).
(c) Compare the results of (b) with the reported expressions for ln \(\gamma_{1} \text { and } \ln \gamma\). Discuss any discrepancy. Can the reported expressions possibly be correct?
