Catalysis and Transition Metal Orbitals

A catalyst is a substance that increase the rate of a reaction without being consumed in the reaction. In general, a chemical reaction involves the breaking and making of bonds. Oxidation/reduction reactions (Redox) involve the net donation or receipt of electrons to or from a given molecule. Transition metals can both lend electrons to and take electrons from other molecules. By giving and taking electrons so easily, transition metal catalysts speed up reactions.

We will focus our attention on redox reactions in this section, but it should be noted that catalysts can be used for many different kinds of reactions and are not limited to oxidation/reduction reactions.
