![### Reaction Rate Study
A chemistry graduate student is studying the rate of this reaction:
\[ 2SO_3 (g) \rightarrow 2SO_2 (g) + O_2 (g) \]
The student fills a reaction vessel with \( SO_3 \) and measures its concentration as the reaction proceeds:
#### Data Table
| **Time (minutes)** | \([SO_3]\) \( (M) \) |
|--------------------|----------------------|
| 0 | 0.0500 |
| 10 | 0.0190 |
| 20 | 0.0117 |
| 30 | 0.00847 |
| 40 | 0.00663 |

#### Questions
1. **Write the rate law for this reaction.**
\[
\text{rate} = k \, [\, ]
\]
2. **Calculate the value of the rate constant \( k \).**
Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.
\[
k = \, [\, ]
\]
---
Here, the student is tasked with analyzing the decrease in the concentration of \( SO_3 \) over time to establish the rate of the reaction and determine the rate constant.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa60cc6ce-11de-444a-af29-e9eb1b50e640%2F1d8f5668-d13a-4448-8b0f-8eee09b87637%2Fo0jcjzh_processed.png&w=3840&q=75)
