Why 3d-series of elements acts as good catalyst?

Text Solution

Verified by Experts

Transition metals and their compounds exhibit catalytic activity due to:
(i) Ability to adopt to multiple oxidation states.
(ii) Translation metals can form complexes reactant molecules using vacant d-orbitals.
This lowers the energy of activation of the reaction and increases rate of the reaction
(iii) Due to the presence of large surface area in finely divided staete.
