Question

Transition elements are usually used as catalysts.

• A. True
• B. False

Answer 1

The correct option is A True

Catalysts are substances which influence the speed of a chemical reaction without themselves undergoing any chemical changes. Generally, transition elements and their compounds are widely used as catalysts. One cause for this property of transition elements is that they are capable of exhibiting different oxidation states and hence they act as both oxidizing and reducing agents at the same time.
