9. COORDINATION COMPOUNDS
4. Answer the following questions.
vii. How stability of the coordination compounds can be explained in terms of equilibrium constants ?
Answer:-
The stability of a complex can be explained in terms of its equilibrium constant (K). A higher value of K indicates greater thermodynamic stability for the complex. Below are the equilibria for complex formation along with their corresponding K values:
Ag+ + 2CN- → [Ag(CN)2]- K = 5.5 × 1018
Cu2+ + 4CN- → [Cu(CN)4]2- K = 2.0 × 1027
Co3+ + 6NH3 → [Co(NH3)6]3+ K = 5.0 × 1033
Among the provided equilibrium constants, [Co(NH3)6]3+ is the most stable complex because it has the highest equilibrium constant value.
