Catalytic Properties: Most of the transition metals and their compounds are used as catalyst. The catalytic activity of transition metals is due to the following reasons.

(i) They show a variety of oxidation states and thereby can form intermediate products with various reactants.

(ii) They are also capable of forming interstitial compounds which can adsorb and activate the reacting species.

Some examples of catalyst are

(i) Iron / molybdenum act as catalyst in the synthesis of ammonia by Haber’s Process.

(ii) Vanadium pentoxide (V2O5) is used for catalytic oxidation of SO2 to SO3

(iii) TiCl4 is employed as a catalyst in the manufacture of polythene.
