A chemical plant uses a reaction between two gases. During testing, the same amounts of the gases react at the same temperature. The time taken to form 0.060 mol of product is measured.
| Pressure in kPa | Time in s |
|---|---|
| 100 | 75 |
| 150 | 50 |
| 200 | 38 |
A chemist predicts that at a pressure of 250 kPa the time taken to form 0.060 mol of product will be less than 38 s.
Explain whether the results and collision theory support the chemist's prediction.
