Dissociation constant

 

Dissociation constant

In chemistry and biochemistry, a dissociation constant is a specific type of equilibrium constant that refers to the extent to which a complexes, molecule, or salt separates or splits into smaller molecules, ions, or radicals in a reversible manner. The dissociation constant is represented by the symbol Kd.

Given the reaction

AxBy <=> xA + yB

It is given by the expression

Kd = [A]x×[B]y×[AxBy]-1


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