medium · Enhanced ACT science
A chemist tracks the concentration of a product in a second-order reaction over time.
| Time (min) | Concentration (M) |
| :--- | :--- |
| 0 | 0.00 |
| 10 | 0.20 |
| 20 | 0.33 |
| 30 | 0.43 |
Based on the table, what is the concentration at t = 15 minutes?
- 0.200 M
- 0.380 M
- 0.265 M
- 0.100 M
