These distortions in coordination geometry lead to a large activation energy if the CFSE is large, even if the product of the ligand exchange reaction is also a stable complex. Complexes of hard acids with hard bases are stable because of the electrostatic component of the CFSE.

Whether you are looking at the replacement of individual water molecules or an overall reaction producing the final complex ion, a stability constant is simply the equilibrium constant for the reaction you are looking at. The larger the value of the stability constant, the further the reaction lies to the right.

For example, the complex of Ni(II) with three ethylenediamine ligands should be chemically similar to the Ni(II) complex with six ammonia ligands. In fact, the equilibrium constant for the formation of the ethylenediamine complex is almost 10 orders of magnitude

Monodentate ligands bind through only one donor atom. Monodentate means "one-toothed." The halides, phosphines, ammonia and amines seen previously are monodentate ligands. Bidentate ligands bind through two donor sites. Bidentate means "two-toothed." It can bind to a metal via two donor atoms at once.
