- A. A slower reaction rate
- B. A faster reaction rate
- C. No change in reaction rate
- D. A completed reaction
Answer
A faster reaction rate
Explanation
The correct answer is A faster reaction rate. This answer directly addresses the question: In a chemical reaction, what does a steeper graph gradient indicate? 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
Misidentifying the rate unit
Students often write the rate of reaction as g s⁻¹ or mol s⁻¹ but forget to include the correct unit for the quantity used (e.g. g s⁻¹ for mass change, cm³ s⁻¹ for volume change, or mol s⁻¹ for moles).
Always pair the rate with the appropriate unit that matches the measured quantity: if you are using mass, use g s⁻¹; if volume, use cm³ s⁻¹; if moles, use mol s⁻¹. Write the unit as a fraction (e.g., g s⁻¹) rather than a product (g s).
