Question

Why do transition metals and their compounds act as good catalysts?

Hint:

Catalysts work by lowering the activation energy for a reaction, often by providing an alternative reaction pathway. Transition metals are especially effective because of their variable oxidation states.

Answer 1

Transition metals and their compounds act as good catalysts because they have multiple oxidation states, which allows them to participate in electron transfer during reactions. Additionally, their ability to form complex intermediates and adsorb reactants on their surface reduces the activation energy, facilitating the reaction.
