A factory wants to speed up the decomposition of hydrogen peroxide, H₂O₂, into water and oxygen. They choose manganese(IV) oxide, MnO₂, as a solid catalyst. Why is MnO₂ suitable as a transition metal catalyst for this process?
- It speeds up the reaction without being used up at the end.
- It makes the reaction slower so less heat is released.
- It is completely consumed to form extra oxygen gas.
- It changes hydrogen peroxide into a different reactant first.
