- A. The reactions are at the same rate
- B. The reaction with the steeper gradient is faster
- C. The reaction with the steeper gradient is slower
- D. The reactants are different
Answer
The reaction with the steeper gradient is faster
Explanation
The correct answer is The reaction with the steeper gradient is faster. This answer directly addresses the question: When comparing two reaction rate graphs, what does it mean if one graph has a steeper gradient than the other? 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 Graph Gradients
Students often confuse the steepness of a graph with the amount of product formed, thinking a higher amount always means a faster reaction rate.
Emphasize that a steeper gradient specifically indicates a faster rate of reaction, regardless of the total amount of product formed.
