Question

Transition elements are frequently used as catalyst because: (A) of variable oxidation state (B) of high ionic charge (C) large surface area of reactants (D) of their specific nature

Tardigrade Admin · Accepted Answer

Because of unpaired d-electrons, transition metals have variable valency which enables them to form unstable intermediate compounds. These intermediates give reaction paths of lower activation energy and, therefore increase the rate of the reaction
