Answer:
The catalytic activity of the transition elements can be explained by two basic facts.
- Owing to their ability to show variable oxidation states and form complexes, transition metals form unstable intermediate compounds. Thus, they provide a new path with lower activation energy, Ea, for the reaction.
- Transition metals also provide a suitable surface for the reactions to occur.
