In chemistry and biochemistry the dissociation constant, abbreviated Kd, is a measure of the extent to which a dissociation reaction

 AB <--> A + B

proceeds at equilibrium.

It is given quantitatively by the expression

Kd = [A]*[B]*[AB]-1

Where [A], [B], and [AB] indicate the concentrations of A, B, and AB, respectively.

See also hydrogen bond.

The dissociation constant is a specific type of equilibrium constant.
