**Chemical Reaction Analysis**
During a chemical reaction, the concentration of Species A was measured as a function of time. The observed concentrations of Species A at various time intervals are presented in the table below. Determine the reaction order and rate constant \( k \) and list the appropriate units. Is Species A being removed or produced?
| Time (min) | Concentration of A (mg/L) |
|------------|---------------------------|
| 0 | 105 |
| 10 | 78 |
| 20 | 62 |
| 30 | 40 |
| 40 | 21 |
| 50 | 1 |
**Table Explanation:**
The table shows the concentration of Species A in milligrams per liter (mg/L) at different time intervals given in minutes (min). The data indicate a decrease in the concentration of Species A over time, suggesting that Species A is being removed during the reaction.
To analyze this data:
1. **Determine the Reaction Order**: Evaluate how the concentration change correlates with time.
2. **Calculate the Rate Constant \( k \)**: Using the reaction order, compute the rate constant and include correct units.
3. **Conclude if Species A is Removed or Produced**: Based on the concentration trend, acknowledge the removal or generation of Species A.
This kind of analysis helps understand the kinetics of the reaction and predict how the concentration of reactants and products change over time.
