WebExcluded volume refers to the steric exclusion of water and cosolvent molecules from the space occupied by solute, an event accompanied by a decrease in translational entropy. Web22 jan. 2024 · The parameter b is interpreted as the effective excluded volume for low densities due to the fact that for low densities ( Ω ≪ V) the contribution of coordinates to the partition function is: V ( V − Ω) ( V − 2 Ω)... ( V − ( N − 1) Ω) ≈ ( V − N Ω 2) N (Equation 5.46) which explains the factor of 1 2 in b. However, the author goes on to say that:
