1.	The catalytic activity of the transition metals and their compound is ascribed to:A. their unfilled d-orbitalsB. their ability of adopt variable oxidation statesC. their chemical reactivityD. their magnetic behaviour
Answer» Correct Answer - B Transition metals are show variable oxidation states `2SO_(2)+O_(2) overset(V_(2)O_(5))rarr 2SO_(3)` `SO_(2)+overset(+5)V_(2)O_(5)rarrSO_(3)+overset(+4)V_(2)O_(4)` `overset(+4)V_(2)O_(4)+O_(2)rarr overset(+5)V_(2)O_(5)`
