Which property of the transition metals makes them good catalyst?
Transition metals acts as catalyst due to the following reasons:
(i) Their partially empty d-orbitals provide surface area for reactant molecules.
(ii) They combine with reactant molecules to form transition states and lowers their activation energy.
(iii) They show multiple oxidation states and by giving electrons to reactants they form complexes and lower their energies.
