Equations analogous to Eqs. (10.15) and (10.16) apply for excess properties. Because ln γ_i is a partial property with respect to G^E∕RT, these analogous equations can be written for ln γ₁ and ln γ₂ in a binary system.
(a) Write these equations, and apply them to Eq. (13.42) to show that Eqs. (13.43) and (13.44) are indeed obtained.
(b) The alternative procedure is to apply Eq. (13.7). Show that by doing so Eqs. (13.43) and (13.44) are again reproduced.
