What is Catalytic Properties?

A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

Key points

  • Explain the reason behind the catalytic activity of transition metals.
  • Identify examples of transition metals used as catalysts in industrial processes.
  • Describe the mechanism by which transition metals catalyze reactions.
  • Relate variable oxidation states to catalytic efficiency.

Common exam trap

Confusing homogeneous and heterogeneous catalysis mechanisms.

Definitions

Term

Catalyst

Meaning

A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

Term

Activation Energy

Meaning

The minimum amount of energy required to initiate a chemical reaction.

Term

Intermediate Complex

Meaning

A temporary, unstable chemical species formed during a reaction mechanism, often involving the catalyst.

Learning objectives

  • Explain the reason behind the catalytic activity of transition metals.
