From the graph, curve 1 was produced by monitoring the decomposition of $100\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ hydrogen peroxide solution, catalysed by manganese(IV) oxide. $2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2$ Which change to the original experimental conditions would generate curve 2?
- Aadding some $0.1\,\text{mol dm}^{-3}$ hydrogen peroxide solution
- Blowering the temperature
- Cusing less manganese(IV) oxide
- Dusing a different catalyst
