AP Chemistry
5.1 Reaction Rates
A student monitors the decomposition of hydrogen peroxide according to the equation \(2\text{H}_2\text{O}_2(aq) \rightarrow 2\text{H}_2\text{O}(l) + \text{O}_2(g)\). The concentration of \(\text{H}_2\text{O}_2(aq)\) measured at various times during the reaction is recorded in the table below.
Based on the data in the table, what is the average rate of disappearance of \(\text{H}_2\text{O}_2(aq)\) between \(t = 10.0\text{ s}\) and \(t = 50.0\text{ s}\)?
| Time (s) | \([\text{H}_2\text{O}_2]\) (M) |
|---|---|
| 0.0 | 1.00 |
| 10.0 | 0.80 |
| 50.0 | 0.20 |
| 60.0 | 0.10 |
