In a reversible reaction, what is the condition when the reaction is at equilibrium?

Options

  1. A∆ r H is maximum
  2. B∆ r S is maximum
  3. C∆ r G is maximum
  4. D∆ r G is minimum

Correct answer

D. ∆ r G is minimum

Step-by-step solution

In a reversible reaction at equilibrium, the change in Gibbs free energy (∆ r G) is at a minimum. This indicates that the system has reached a stable equilibrium state.
