## Gas Phase Decomposition of Dimethyl Ether

The following data are for the gas phase decomposition of dimethyl ether at 500 °C.

### Chemical Reaction
**CH₃OCH₃(g) → CH₄(g) + H₂(g) + CO(g)**

### Observed Data 
| Time (min) | [CH₃OCH₃] (M)     |
|------------|--------------------|
| 0          | 3.66 x 10⁻²       |
| 23.8       | 1.83 x 10⁻²       |
| 47.6       | 9.15 x 10⁻³       |
| 71.4       | 4.58 x 10⁻³       |

### Instructions:
1. **Calculate the Half-life:** 
   The half-life observed for this reaction is \_\_\_\_\_\_ min.

2. **Determine the Rate Constant:**
   Based on these data, the rate constant for this \_\_\_\_\_\_ order reaction is \_\_\_\_\_\_ min⁻¹.

### Additional Notes
- **Hint:** It is not necessary to graph these data.
  
### Answer Submission
- Select the appropriate reaction order from the given options (zero, first, second) and determine the rate constant accordingly.

Submit your answers using the provided options and ensure to check your calculations for accuracy.

### Interactive Components
- Dropdown menu to select the reaction order (zero, first, second)
- Input fields to enter the calculated half-life and rate constant
- Buttons: "Submit Answer" and "Try Another Version" for response verification and additional practice respectively.

#### Example Calculation
For a decomposition process, you often use the integrated rate laws depending on the order of the reaction to find the half-life and the rate constant. Please use the data accordingly to derive these values.
