their ability to adopt variable oxidation states

Vedclass · Answer

(C) The catalytic activity of transition metals and their compounds is primarily attributed to their ability to adopt variable oxidation states and form complexes. For example,in the contact process,$V_{2}O_{5}$ acts as a catalyst: $2SO_{2} + O_{2} \xrightarrow{V_{2}O_{5}} 2SO_{3}$ This occurs because vanadium can easily switch between oxidation states: $SO_{2} + V_{2}O_{5} \longrightarrow SO_{3} + 2VO_{2}$ $2VO_{2} + \frac{1}{2}O_{2} \longrightarrow V_{2}O_{5}$

The catalytic activity of transition metals and their compounds is ascribed mainly to
