The excess second virial coefficient of (0.500CO + 0.500CO2)(g) has been determined at temperatures 303.15 K, 313.14 K, 323.15 K, 333.15 K, and 343.15 K. The pressure-change-ofmixing method was used. The excess molar enthalpy was derived as well as unlike-interaction second virial coefficients which
The excess second virial coefficient for (1,1,1,2-tetrafluoroethane + propane) has been measured at temperatures of 299.5 K, 313.15 K, 328.15 K, and 343.15 K, using the pressure-change-on-mixing method. The excess enthalpy and unlike-interaction second virial coefficients are also reported. The resu
