| Abstract: | The heat of mixing of liquid argon (component 1) and liquid carbon monoxide has been measured by direct calorimetry for several mixtures of composition ranging from x1 ? 0.2 to x1 ? 0.8 at 85.79 K. At this temperature HE is positive and an almost parabolic function of mole fraction, with a maximum value of HE = 95.9 J mol?1 at x1 = 0.569.The experimental results are compared with those derived from the Gibbons-Rigby equation of state, and from conformal solution theory. |
