Question

Catalytic activity of transition metals depends on:

• A. their ability to exist in different oxidation states
• B. the size of the metal atoms
• C. the number of empty atomic orbitals available
• D. none of these

Answer 1

The correct option is A their ability to exist in different oxidation states

The transition metals and their compounds are known for their homogeneous and heterogeneous catalytic activity. This activity is ascribed to their ability to adopt multiple oxidation states and to form complexes.
