Question

A. It allows for the escape of products
B. It prevents the forward reaction from occurring
C. It enables the system to reach equilibrium
D. It increases the rate of reaction

Answer

It enables the system to reach equilibrium

Explanation

The correct answer is It enables the system to reach equilibrium. This answer directly addresses the question: What is the significance of a closed system in reversible reactions? 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 Hydrated and Anhydrous Forms

Students often confuse hydrated copper sulfate (CuSO4·5H2O) with anhydrous copper sulfate (CuSO4) and their properties.

Remember that hydrated copper sulfate contains water molecules and appears blue, while anhydrous copper sulfate is white and does not contain water.
