Overall reaction order

[705340227]

Can the overall reaction order be zero? In that case, what determines the rate of reaction if it is not the concentration of the reactants?

[Riddhi Mehta 2C]

I believe it can be if all the reactants in the reaction are zero-order. The overall order of the reaction is simply based on all the reactants so if each reactant order is zero then the order would be zero and I guess the rate law would only depend on the rate constant.

[Ephrem Gerald 2A]

This is very rare, and I haven't seen it yet but I believe that theoretically yes, a reaction can have an overall order of zero if all the reactants are zero order as well. It just means that the speed of the reaction is solely dependent on the rate constant.

[Arya Adibi 1K]

It would be soley based on the rate constant, but this situation probably won't come up as it is very rare

[LarisaAssadourian2K]

If all the reactants are zero order, then it would technically be possible. However, that case doesn't occur very often.

[Dominic Benna 2E]

The overall reaction order can be zero if all reactants are zero-order. This would mean that the rate of the reaction would just be based on the constant, and not the initial values of the reactants.

It is possible but not likely. But usually at least one reaction is not zero-order.

[FionaHunter21]

I believe it only relies on k and occurs when there is some catalyst or enzyme involved that is fully saturated.

[Aayushi Jani 3A]

As others have said, it is possible if all the individual reactants are zero-order as well. However, I haven't seen any problems like that in the textbook or Sapling, so I assume it is rare and doesn't really occur. I would assume that the rate of the reaction would be based on the rate constant only.

[aashmi_agrawal_3d]

It can but it is very rare. It would then be based off of the rate constant.

[Lilly Catarozoli 1B]

As others said, it is possible but not very likely!

[Lesly Lopez 3A]

Hey you guys, simply here to affirm the statements above. I believe it can be a zero reaction only if all the reactants in the reaction are zero-order although it is not often seen. Still, it is not impossible just not really seen.

[Brian Acevedo 2E]

Theoretically yes, but given that the only thing that would determine the rate of the overall reaction at that point would be the rate constant k, it isn't exactly a common phenomenon.

[Siwa Hwang 3G]

yes it can if all the reactants in the reactions are zero order

[Emma Strassner 1J]

It is rare, but theoretically yes. All of the reactants would have to be zero order for this to occur.

[Jacob Schwarz-Discussion 3I]

If all of the reactants were to be zero-order, the reaction would be a zero order reaction.

[Carolina Gomez 2G]

If the overall reaction order were to be zero that would mean all reactants have zero order. The rate law would then just be equal to the rate constant (k) and would not depend on the concentrations.

[Ashley Lopez 3J]

This could only happen if all the reactants are in zero-order. This means that the rate law would just equal to k and not be dependent on the concentrations.

[Ashley Wagner 2A]

For the overall reaction to zero-order, all of the reactants would be zero-order and the rate law would only depend on k.

[Edgar Velazquez 2K]

It should be possible, but I assume it's very rare. As students, we'll probably never see a fully zero-order reaction.

[kentbui1d]

If the sum of everything is zero, then the overall reaction would be. Though it would be really rare.

[FrancescaHawkins2H]

If all of the reactants in a reaction are zero order then yes, I believe the overall equation itself would also be zero order, since it is the sum of the order of the reactants. The rate law then would depend on k. I can't imagine, however, that this would happen very often, although it is possible.

[Trisha Badjatia 2L]

Hi! Theoretically, the overall reaction order can be zero if changes in each of the reactants have no impact on the reaction rate, which is highly unlikely. Hope that helps!
