- A. It decreases the reaction rate
- B. It increases the reaction rate
- C. It has no effect on the reaction rate
- D. It stops the reaction
Answer
It increases the reaction rate
Explanation
The correct answer is It increases the reaction rate. This answer directly addresses the question: What is the effect of increasing the surface area on the rate of a chemical reaction? 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
Surface Area Misunderstanding
Students often think that increasing surface area has no effect on reaction rate.
To fix this, remember that increasing surface area allows more particles to collide, which usually increases the reaction rate.
