**Pre-lab Question #10-4: Reaction Rate Analysis**

In this exercise, you are provided with experimental data concerning the reaction between substances A and B, following the stoichiometric equation:

\[ 3A + 2B \rightarrow 2C + D \]

The table below summarizes the initial concentrations of reactants A and B and the rate of appearance of product C:

| [A], M       | [B], M  | Rate of Appearance of C, M/hr  |
|--------------|---------|--------------------------------|
| 1.0 x 10^-2  | 1.0     | 0.300 x 10^-6                  |
| 1.0 x 10^-2  | 3.0     | 8.10 x 10^-6                   |
| 2.0 x 10^-2  | 3.0     | 3.24 x 10^-5                   |
| 2.0 x 10^-2  | 1.0     | 1.20 x 10^-6                   |
| 3.0 x 10^-2  | 3.0     | 7.30 x 10^-5                   |

**Analysis Task:**

Using the data provided, perform the following analysis:

**Pre-lab Question #10-4 (d): Determine the correct unit of the rate constant, \( k \).**

**Multiple Choice:**

- \( \text{M}^{-4} \cdot \text{s}^{-1} \)
- \( \text{M}^{-3} \cdot \text{s}^{-1} \)
- \( \text{M}^{-4} \cdot \text{hr}^{-1} \)
- \( \text{M}^{-3} \cdot \text{hr}^{-1} \)

Conduct a detailed examination of the data, considering the units involved and the overall reaction order, to identify the correct unit for the rate constant \( k \).
