Abstract |
The total vapor pressure of liquid mixtures of xenon and cyclopropane has been measured at 161.39 K (the triple-point of xenon) and at 182.33 K (the triple-point of dinitrogen oxide), as a function of composition. At 182.33 K the liquid densities were also measured. The mixtures show positive deviations from Raoult s law. Both the excess molar Gibbs energy (G(m)(E)) and the excess molar volume (V-m(E)) were calculated from the experimental data. For the equimolar mixture, G(m)(E) = 90.6 J mol(-1) at 161.39 K, G(m)(E) = 124.1 J mol(-1) at 182.33 K, and VEmE = -0.758 cm(3) mol(-1) at 182.33 K. The excess molar enthalpy (H-m(E)) could be estimated from the temperature dependence of G(m)(E) and found to be -168 J mol(-1). The results were interpreted using the 1cLJ perturbation theory of Fisher et al. |
