All reactants zero order?

Postby Leonardo Le Merle 1D » Thu Mar 12, 2020 11:34 am

Could there ever be a reaction in which all reactants are zero order and thus the reaction itself is zeroth order? What would be an example of this?

I mean, I don't see a scenario where it couldn't be possible. . but yeah just know that these type of reactions are typically found when a material that is required for a reaction to proceed-surface/catalyst-is saturated by the reactants. Hope this helps! :D

very rare but yes it can occur

Yes, it could happen if they all depend on the presence of a catalyst.

quoting in case an example comes up

If the catalyst was saturated with just reactants, then the catalyst would be the main driving force of the reaction and it would only be dependent on reaction rate, or k, in a zeroth order reaction. This would be possible in a real life reaction if the catalyst was saturated completely and the concentration of the reactants was meaningless.

In theory I do believe this is possible, however I am not of what an example would be. Could somebody please give a real life application in which this would be the case.
