The curves below represents the change in mass when equal masses of powdered zinc and zinc granules were reacted with excess 2 M hydrochloric acid. Study them and answer the question below

The curves below represents the change in mass when equal masses of powdered zinc and zinc granules were reacted with excess 2 M hydrochloric acid. Study them and answer the question below

Which curve represents the reaction with zinc granules? Explain answer.

---

Curve X represents zinc granules. This is because the granules have a small surface area hence reacts slowly. The rate of change in mass therefore will be slow
