In the laboratory, hydrogen gas of good purity can most easily be obtained by the reaction of a strong acid, like sulfuric acid, on a reactive metal, such as zinc:

\[ \text{Zn(s)} + \text{H}_2\text{SO}_4\text{(aq)} \rightarrow \text{ZnSO}_4\text{(aq)} + \text{H}_2\text{(g)} \]

Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 173.4 g of solid zinc and 82. mL of 5.0 M sulfuric acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below.

Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on.

| Vessel | Volume | Temperature | Initial Rate of Reaction |
|--------|--------|-------------|--------------------------|
| A      | 5.0 L  | 11.0 °C     | ?                        |
| B      | 5.0 L  | 9.0 °C      | ?                        |
| C      | 5.0 L  | 12.0 °C     | ?                        |
| D      | 5.0 L  | 7.0 °C      | ?                        |

**Diagram Explanation:**

The table above shows four columns: 

1. **Vessel**: Labels each reaction vessel as A, B, C, or D.
2. **Volume**: Indicates the volume of each vessel, which is consistently 5.0 liters.
3. **Temperature**: Lists the temperature of each reaction vessel, ranging from 7.0 °C to 12.0 °C.
4. **Initial Rate of Reaction**: Allows for ranking the expected initial reaction rates in order based on the provided temperatures.
