Why is it necessary for a reversible reaction to reach a minimum free energy at equilibrium?

Options

  1. ATo maximize the entropy change
  2. BTo ensure that the reaction occurs at a very high rate
  3. CTo allow for the formation of multiple products
  4. DTo maintain a stable equilibrium state

Correct answer

D. To maintain a stable equilibrium state

Step-by-step solution

In a reversible reaction, the free energy of the system must reach a minimum at equilibrium to maintain a stable equilibrium state. If it is not at a minimum, the system would spontaneously change to a configuration of lower free energy.
