What does it mean for the reactants of a zero order reaction?

it means that the rate at which a reaction occurs is not dependent on the concentration of reactant.

For a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants.
The differential rate law for zero-order is rate = (-1/a)(d[A]/dt) = k[A]^0 = k, so you can see how the rate does not depend on [A].
This can happen when a catalyst or enzyme is required in the reaction, and that catalyst or enzyme has become saturated, so increasing the concentration of the reactants does not increase the rate of the reaction.

It just means that the rate of reaction is not dependent on that element which is zero order. As in d[A]/dt=-k[A]^0=-k, the rate is solely dependent on k.

For a zero order reaction, the rate of the reaction is not dependent on the concentration of the reactants but simply on k, which varies depending on the specific reaction occurring under a certain set of conditions.

Zero order means that the reaction rate does not depend on the concentration of the reactants
First order means that the reaction rate depends on the concentration of one reactant
Second order means that the reaction rate depends on the concentration of 2 reactants

It means that the rate does not vary with the increase or decrease in the concentration of the reactants.

The concentration of a reactant that is zero order has no effect on the rate of its reaction. The concentration of this species can triple or halve but the rate of the reaction will stay constant. It is therefore not included in the rate law of that reaction.

From what I understand, it practically means that the rate of the reaction is not dependent. It does not depend on whether the rest of the reaction increases or decreases. As in d[A]/dt=-k[A]^0=-k, the rate is solely dependent on k. Hope that kinda clears things up.

The concentration of the zero order reactants does not affect the rate of the overall reaction. Sometimes this is because the reactant in question is not directly involved in the rate-limiting step.

Hello! For a zero-order reaction, the overall rate of the reaction is not dependent on the concentration of the reactants but rather it is dependent on k. However, depending on the set of conditions and type of reaction it varies.

I believe that in zero-order reactions you wouldn't see a pattern between the concentrations and the rates of the reaction. The simplest way I can explain it.

Since a zero-order rate law will be k[A]^0, which is just k, that means that the rate does not depend on the concentration of the reactant(s).

Zero Order means the reaction isn't affected by the concentration. The equations that come with it are [A]=-kt+[A0], d[A]=-kdt, t(1/2)= [A0]/ (2k).

order of a reaction: with respect to one of the reactants, the order of a reaction is equal to the power to which the concentration of that reactant is raised in the rate equation.

The rate of the reaction is not dependent on the amount of reactant in the case of a zero-order. If you think about it, a zero-order rate is written as rate = k*[reactant]^0. Anything to the 0th power is automatically 1, so the rate simply becomes rate = k*1 = k.

The reactants of a zero-order reaction do not affect how fast the reaction goes. In the rate law for this reaction, all reactants are put to the zeroeth power, so no matter what their concentration is, their contribution to the rate law will be multiplying the rate law by 1.

A zeroth-order reaction is one whose rate is independent of concentration; its differential rate law is rate = k. We refer to these reactions as zeroth order because we could also write their rate in a form such that the exponent of the reactant in the rate law is 0: rate=−Δ[A]Δt=k[reactant]0=k(1)=k.

In a zero order reaction, the concentration of the reactants does not affect the reaction rate. It is only dependent on the k value. This is called a "zero order reaction" because anything to the power of zero is one.

Hope this helps!

For a zero order reaction, that means the integrated rate law is [A]=-kt+[A]o, where we can see that the rate of the reaction is only impacted by k, and is not affected at all by the concentrations of the reactants.

Hi! A zero order reaction just means that the rate of the reaction is only dependent on the rate constant, k, and not on the concentration of the reactants.
