Catalysts

Postby Matthew ILG 1L » Mon Mar 09, 2020 1:07 pm

In today's lecture(3/9/20) Dr. Lavelle gave an example of how Nitric Oxide catalyses the conversion of oxygen to ozone in lower atmosphere.
He stated that NO(g) is a catalyst. However, is O2(g) also a catalyst?
It is not formed at any point during the process, so I assume it is not an intermediate.

I do not think that O2 is a catalyst, but rather just part of the reaction. The intermediates are NO2 and O, while the only catalyst is NO.

O2 is not a catalyst, simply a reactant in the overall reaction. The process itself refers to the conversion of oxygen to ozone, so oxygen is a simply a reactant in this process, otherwise there would be no reactants. So yes, nitric oxide (NO) is the only catalyst in this reaction.

NO is the only catalyst and O2 is simply just a reactant because it is not reformed in the products.

From my understanding in lecture, the catalyst in this reaction is NO, not O2

Dr. Lavelle also noted the difference between intermediates and catalysts in which catalysts are initially there and then reformed while intermediates are created and consumed in the reaction.
