A student investigated the rate of catalytic decomposition of hydrogen peroxide using manganese(IV) oxide.
The volume of oxygen gas produced was measured every 15 seconds. The results are shown in the table below.
| Time in seconds | 0 | 15 | 30 | 45 | 60 | 75 | 90 |
|---|---|---|---|---|---|---|---|
| Volume of oxygen gas in cm3\text{cm}^3cm3 | 0 | 32 | 54 | 68 | 76 | 80 | 80 |
On the grid, plot the results shown in the table.
Draw a curve of best fit.
