A student investigates the rate of oxygen production during the decomposition of hydrogen peroxide using the enzyme catalase. The student measures the volume of oxygen gas collected in a gas syringe every 5 minutes. The table shows the results of this investigation:
| Time (minutes) | Volume of oxygen collected (cm3\text{cm}^3cm3) |
|---|---|
| 0 | 0 |
| 5 | 45 |
| 10 | 62 |
| 15 | 75 |
Calculate the difference between the rate of oxygen production in the first five minutes and the rate in the final five minutes.
