Question
- A. A system where reactants can escape
- B. A system where products can escape
- C. A system where no substances can enter or leave
- D. A system that is open to the environment
Answer
A system where no substances can enter or leave
Explanation
The correct answer is A system where no substances can enter or leave. This answer directly addresses the question: Which of the following best describes a closed system in the context of 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
Confusing Dynamic Equilibrium
Students often think that dynamic equilibrium means the reactions have stopped.
Remember that dynamic equilibrium means the forward and reverse reactions are still occurring at the same rate.
