In the diagram, curve X was produced by monitoring the decomposition of $100\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ hydrogen peroxide, with manganese(IV) oxide acting as the catalyst. Which change to the starting experimental conditions would result in curve Y?
- Aadding some $0.1\,\text{mol dm}^{-3}$ hydrogen peroxide
- Badding water
- Clowering the temperature
- Dusing less manganese(IV) oxide
