Reaction Moment and Equilibrium Constant

When changes in the concentration of the reaction partners can be measured directly, say by an optical method, the analysis of equilibrium properties is based on Eqs. (3.23) and (4.42) of parti. The electric field

It is frequently observed that the reaction moment AM is dominated either by the induced dipole term M, ) or by the permanent dipole term Af(p). It is therefore useful to follow Eq. (3.10) and to write AM in two terms  

In the case of pure induced polarization the solute molecules Bj may be considered as polarizable spheres associated with a molecular permittivity (s )j and Py = 0. When these molecules are immersed in a large quantity of nonpolar solvent the total permittivity of the solution s is practically that of the solvent. 

For particles of uniaxial anisotropic polarizability ay, Eqs. (3.2) and (3.23) with M = Af(a) are combined with Eq. (3.29). Since Nj = N np the resulting expression reads
