14.3: Effect of Concentration on Reaction Rates: The Rate Law
A Because no concentration term appears in the rate law, the rate constant must have M/s units for the reaction rate to have M/s units. B The rate law tells us that the reaction rate is constant and independent of the N 2 O concentration. That is, the reaction is zeroth order in N 2 O and zeroth order overall.

kinetics – Can rate constant depend upon the concentration of reactants …
There is the reaction rate constant — in your equation k r, and there is the rate of reaction — in your equation r and sometimes expressed by v. Depending on the order of a reaction, the overall rate of reaction may, but need not depend on the concentration of the reactants available.

How is the reaction rate constant affected by concentration?
Rate is dependend on concentration, but for the same concentration, a reaction with a higher rate constant will proceed faster, thus remove $ce A$ fast and have a more negative slope. Lets compare for the two $k$ values, $k_ {upper}$ and $k_ {lower}$.

Kinetics – Why doesn’t a change in concentration affect the rate constant?
If the concentration of one of the reactants increases, the rate of reaction will also increase, the rate constant, k will not change. If the pressure increases, the concentration of all the reactants will increase and so the rate of reaction will also increases.

Why is the rate of a chemical reaction not constant? – Quora
The rate constant of a chemical reaction is denoted by k. According to rate law R = k [reactant]^ order Thus according to the rate law if the value of concentration of the reactant is 1 then r=k. Thus k can be defined as the rate of chemical reaction when the concentration of the reactant is unity.

If a zero order reaction does not depend on the concentration then why …
Since at high concentration, all the active sites at the catalyst surface is occupied / saturated where decomposition of NH3 can occur after adsorption. So increase or decrease in concentration from this high value does not affect the saturation, so rate doesn’t depend on NH3 concentration. 6 Swami Viswanathan

Rate constant does not depend upon unit of concentration for … – Vedantu
Evidently, the Rate constant does not depend upon the unit of concentration for reaction of first order. Hence, the correct option is (B) first. Additional information: Other names for rate constant (k) are -velocity constant -speed constant -reaction rate constant Note: Rate of the reaction (r) is change in concentration with respect to time.

What does it mean if the rate constant is negative? [FAQ!]
Rate constant is a constant and does not depend on concentration of reactants. However, it depend on temperature of reaction. One can predict the order of reaction by units of rate constant. However, it depend on temperature of reaction.
