### Pre-lab Question #10-1: Reaction Order Determination

#### Scenario:
A reaction between substances A and B has been found to give the following data for the reaction:

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

#### Data Table:

| [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                |

#### Question:
Using the data above, determine the following:

**Pre-lab Question #10-1: (a) Order of the reaction with respect to A and B**

#### Multiple Choice Options:
1. ⬜ 1st order with respect to A, and 2nd order with respect to B
2. ⬜ 2nd order with respect to A, and 2nd order with respect to B
3. ⬜ 2nd order with respect to A, and 3rd order with respect to B
4. ⬜ 3rd order with respect to A, and 2nd order with respect to B

---

**Explanation of Data and Graphs:**

In this exercise, you will analyze the provided reaction data to determine the reaction order with respect to reactants A and B. The data table includes initial concentrations of A and B, alongside the observed rates of formation of product C. This will help in deriving the rate law and subsequently the reaction orders.

When evaluating these orders:
- Compare pairs of data where the concentration of one reactant is held constant while the other is varied.
- Notice how the rate of reaction changes with alterations in reactant concentrations.
