Reversible reactions and dynamic equilibrium
Question
- A. The reaction has stopped completely
- B. The concentrations of reactants and products remain constant
- C. The forward reaction is faster than the reverse reaction
- D. All reactants are converted to products
Answer
The concentrations of reactants and products remain constant
Explanation
The correct answer is The concentrations of reactants and products remain constant. This answer directly addresses the question: What does it mean when a reversible reaction reaches equilibrium? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Reversible Reactions
Students often think that reversible reactions only go in one direction and do not understand that products can react to form the original reactants.
To fix this, students should remember that in a reversible reaction, the products can react to regenerate the reactants, illustrating the dynamic nature of these reactions.
