$mol$$dm^{-3}$ | $Reaction Time (s)$ | $Rate of Reaction$ |
| 1 | 0.045 | 0.100 | 3.59 | |
| 2 | 0.045 | 0.050 | 7.20 | |
| 3 | 0.045 | 0.025 | 14.00 | |
| 4 | 0.0225 | 0.100 | 7.05 | |
1.Fill in the table with the respective rate of reaction for each trial.
2.Sketch the graph for rate vs [KI] and state the order of reaction with respect to KI.
3.Determine the order of reaction with respect to hydrogen peroxide using the data table.
4.Suggest two further experiments that could be done to determine the rate expression.
5.Suggest an advantage or a disadvantage about using a simulation to collect data.
