Abstract

The work required to couple a hard sphere solute into a solvent of molecules interacting through a square well potential is calculated by two methods. First a virial series approximation is used, and then an approximate integral equation is used. Both approximations show how the solvation work changes with the size of the solute particle. We find that the solvation work for a solute of size ∼R has the form Ws(R) ≈ a + bR + cR2 + dR3.
