- B. To allow for continuous reaction
- C. To increase the temperature of the system
- D. To ensure constant pressure
Answer
To prevent the escape of reactants and products
Explanation
The correct answer is To prevent the escape of reactants and products. This answer directly addresses the question: Why is a closed system required when applying equilibrium predictions? 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
Understanding Closed Systems
Students often forget that a closed system prevents the escape of reactants or products, which is essential for maintaining equilibrium.
Emphasize that a closed system allows for accurate predictions of equilibrium shifts because it keeps the concentrations of reactants and products constant.
