Transition elements are frequently used ...

Transition elements are frequently used as catalyst because:

A

or variable oxidationk state

B

of high ionic charge

C

large surface area of reactants

D

of their specific nature

Text Solution

Verified by Experts

The correct Answer is:
A
Because of unparied which d-electrons, transition metals have variable varlency which enables them to form unstable intermediate compounds. These intermediates give reaction path of lower activation enrergy and, therefore increase the rate of the reaction.
