CONCEPT:

Thermodynamic Stability

  • Thermodynamic stability refers to the extent to which a compound or complex resists decomposition or transformation into another compound.
  • It is determined by the energy changes associated with reactions or transformations, typically involving Gibbs free energy.
  • In the context of coordination complexes, the stability constant (formation constant) is a key indicator.

EXPLANATION:

  • Activation energy refers to the energy barrier for a reaction to proceed, which is more related to reaction kinetics than thermodynamic stability.
  • Reaction rate is a kinetic parameter that describes how quickly a reaction proceeds; it does not directly indicate thermodynamic stability.
  • The stability constant (formation constant) measures the equilibrium constant for the formation of a complex. A higher stability constant indicates greater thermodynamic stability of the complex.

The correct answer is: 2) Stability constant
