WebMar 21, 2014 · The osmotic coefficient first increases with increasing the concentration ratio then saturates. The magnitude of the saturation plateau increases with increasing polymer concentration. It is well known that this value corresponds to the fraction of the osmotically active counterions in low salt concentration regime (see for review [ 2 , 9 , 10 ]). WebOther articles where virial coefficient is discussed: gas: Equation of state: virial coefficients and depend only on the temperature and the particular gas. The virtue of this equation is that there is a rigorous connection between the virial coefficients and intermolecular forces, and experimental values of B(T) were an early source (and still a … WebThe first step in obtaining a closed expression for virial coefficients is a cluster expansion [1] of the grand canonical partition function Here p is the pressure, V is the volume of the vessel containing the particles, kB is Boltzmann's constant, T is the absolute temperature, λ = exp [μ / (kBT)], with μ the chemical potential. great horn financial
