Monte Carlo data of dilute solutions of large spheres in binary hard sphere mixtures

Monte Carlo (MC) simulation data for additive binary hard sphere mixtures a re reported for dilute concentrations of the large sphere. Using a single o ccupancy linked cell method, binary hard sphere solutions with a size ratio of 5 are simulated at high reduced density and low concentration of the la rge sphere. Data for the solute-solvent pair distribution function show tha t at the lowest concentrations of the large sphere simulated, the Boublik-M ansoori-Carnahan-Starling-Leland (BMCSL) equation underestimates the contac t value; whereas the recently proposed Henderson-Chan (HC) equation gives a good prediction. For the solute-solute contact value at the colloidal limi t, the MC data lie between the two predictions. The BMCSL equation underest imates, while the HC equation overestimates, the correct solute-solute cont act value.
