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.
