The equilibrium constant values for the reaction of Ni 2 in aqueous solution with an amine to form the corresponding ammonia, en, and dien complexes increase in the order dien>en>ammonia. Why is this the case

This is due to stability constant

Explanation:

A stability constant (formation constant, binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the complex.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
