$\Delta E_m=\Delta H_m-P\Delta V_m$ (3.8.6)

(3.8.6)

$\Delta C_P{|}_m=-RT\sum _i{n}_i[2{(\partial \ln {\mathrm{\Gamma }}_i/\partial T)}_{P,x_i}+T{({\partial }^2\ln {\mathrm{\Gamma }}_i/\partial T^2)}_{P,x_i}].$ (3.8.7)

(3.8.7)

A corresponding equation is obtained for C_V|m. The various partial derivatives called for in Eqs. (3.8.3)– (3.8.7) may be determined via Eqs. (3.5.1) and (3.5.2). The above expressions all properly reduce to the results of Section 2.5 for ideal solutions.
