Question

How is the stability constant K of a complex related to its thermodynamic stability?

Answer 1

The stability constant (K) of a complex is directly proportional to its thermodynamic stability. A higher value of K means the complex is more stable and less likely to dissociate, while a lower value of K indicates lower stability. A large K corresponds to a more negative Gibbs free energy change (ΔG⁰), making complex formations more favourable.

Therefore, the stability constant K of the complex is directly related to the thermodynamic stability, that is it is directly proportional to it.
