WebUsing pK a values to predict reaction Equilibria. By definition, the pK a value tells us the extent to which an acid will react with water as the base, but by extension, we can also calculate the equilibrium constant for a reaction between any acid-base pair. Mathematically, it can be shown that: K eq (for the acid base reaction in question) = 10 Δ … WebPredicting pKa. One of the most important physicochemical properties of small molecules and macromolecules are the dissociation constants for any weakly acidic or basic groups, …
