Answer: Thermodynamic stability is determined by Stability Constant.
Explanation:
- Thermodynamic Stability: This refers to the energy change that occurs when a system moves from an initial state to an equilibrium state. It is a measure of the extent to which a complex will form or transform into another species under specific conditions when given infinite time.
- Stability Constant (Ks): Also known as the formation constant, it is the equilibrium constant for the formation of a complex in solution. A higher stability constant indicates a more thermodynamically stable complex.
- Kinetic vs. Thermodynamic Stability: Options B (Activation Energy) and C (Rate of Reaction) relate to Kinetic Stability. Kinetic stability deals with how fast a reaction occurs, whereas thermodynamic stability deals with the energy difference between reactants and products (ΔG).
