Zinc reacts with dilute hydrochloric acid to produce hydrogen gas.
The rate of reaction between zinc and dilute hydrochloric acid at 20 ∘C20\,^\circ\text{C}20∘C was investigated using different sizes of zinc pieces.
The mass of zinc and all other conditions were kept the same.
The results are shown in Table 1.
Table 1
| Size of zinc pieces | Volume of hydrogen gas collected in 3 minutes in cm3\text{cm}^3cm3 |
|---|---|
| Large granules | 12 |
| Small granules | 34 |
| Powder | 78 |
State, using the information in Table 1, the effect of the surface area of the zinc on the rate of this reaction.
