Hydrogen peroxide, $\text{H}_2\text{O}_2$, breaks down to make water and oxygen: $2\text{H}_2\text{O}_2(aq) \rightarrow 2\text{H}_2\text{O}(l) + \text{O}_2(g)$. Manganese(IV) oxide acts as a catalyst for the decomposition reaction. This reaction is studied in four experiments. Which statement is the correct one?
- AExperiment 1 produces less gas than experiment 4, but at the same rate.
- BExperiment 2 produces more gas than experiment 1, but at the same rate.
- CExperiment 2 and experiment 4 each produce the same volume of gas, but at different rates.
- DExperiment 3 and experiment 4 each produce the same volume of gas and at the same rate.
