Zinc metal reacts with dilute sulfuric acid to produce hydrogen gas.
The rate of reaction between zinc and dilute sulfuric acid at 20degC was investigated.
The investigation was carried out using different sizes of zinc pieces, while keeping the total mass of zinc and all other conditions constant.
The results are shown in Table 1.
| Size of zinc pieces used | Volume of hydrogen gas produced in three minutes in cm3\text{cm}^3cm3 |
|---|---|
| Large granules | 12 |
| Small granules | 35 |
| Zinc powder | 72 |
State, using the information in Table 1, the effect of the surface area of the zinc on the rate of this reaction.
