Catalytic properties of transition elements

Catalytic properties    of Transition Element-

:- some of the transition metals and their salts act as catalyst . For example, finely divided iron act as a catalyst in Haber's process for the manufacturer of ammonia. Finely divided nickel is used as a catalyst in the hydrogenation of oil to fat in the manufacturer of vegetable ghee . Decompression of bleaching powder solution is catalysed by Cobalt salt . MnO² is used as a catalyst in the decompression of H²O² solution in contact process .

   The catalytic power is probably due to the use of (n_1) d-orbitals or due to the Formation of some interestital compound which absorb and activate the reacting substance.
