Question
Chemistry Question on d block elements
Transition elements are generally used as catalyst because
A
they form different intermediate compounds
B
they are heavy metals
C
they are diamagnetic
D
they possess high melting points
Answer
they form different intermediate compounds
Explanation
Solution
The transition element with varying oxidation states may form intermediate compounds with one of the reactants. These intermediates provide a new path with lower activation energy and get decomposed on reaction with the other reactant regenerating the catalyst.
