Chemical equilibrium state is_______________?
Correct answer: A. dynamic state
- A. dynamic state
- B. static state
- C. free state
- D. unidirectional state
Explanation
Chemical equilibrium is dynamic because the forward and reverse reactions continue simultaneously at equal rates. Concentrations remain constant macroscopically, but molecules are still reacting microscopically. The likely mistake is choosing static state because no net concentration change is observed, which does not mean the reactions have stopped.

About Reversible Reactions
A reversible reaction proceeds in both forward and backward directions, so reactants and products continue changing until dynamic equilibrium is established. The topic covers the meaning of equilibrium, the equality of forward and reverse rates, and how concentration, pressure and temperature disturb equilibrium, which is separate from the rate at which equilibrium is reached.
