Homogeneous vs. Heterogeneous Catalysts

[Kyle Walsh 2J]

Hi! I was just looking over the end of the last lecture and the two types of catalysts seemed to be important. Is there any effects of each one that I should explicitly know about when it is involved in a reaction? Will we be asked to identify which of the two types is more effective in a given scenario?

Be able to identify that Homogenous catalysts are in the same phase as the reactants! Lavelle lieks to use real examples so be sure to review the catalyst NO(g) in the the biochemical reaction that produces ozone! Heterogenous catalysts are in a different phase as the Reactants (like a solid enzyme involved with a reaction of liquids)

[Randi Ruelas 1G]

Homogeneous catalysts are those which exist in the same phase (gas or liquid ) as the reactants, while heterogeneous catalysts are not in the same phase as the reactants. Homogeneous catalysts allow for greater interaction with the reaction mixture than heterogeneous catalysts. Heterogeneous catalysis is very important because it enables faster, large-scale production and the selective product formation.
