Hydrogen peroxide breaks down slowly at room temperature. $2\text{H}_2\text{O}_2(aq) \rightarrow 2\text{H}_2\text{O}(l) + \text{O}_2(g)$ This reaction may be catalysed by adding manganese(IV) oxide. Which statement is correct when a catalyst is added to the aqueous hydrogen peroxide?
- AThe catalyst increases the activation energy for the reaction.
- BThe catalyst is used up during the reaction.
- CThe gas syringe fills up more quickly when the catalyst is added.
- DThe total amount of oxygen produced increases when the catalyst is added.
