WebWhich of the following are correct for zero-order reactions? Check all that apply. • View Available Hint (s) The concentration of the reactants changes nonlinearly. A higher concentration of reactants will not speed up the reaction. The rate of reaction does not equal the rate constant. WebApr 24, 2024 · where order of the reaction w.r.t. $\ce{A}$ is $-1$ and order of the reaction w.r.t. $\ce{B}$ is $+1$. So, overall order of the reaction $=(-1)+(1) = 0$. So, it is a zero order reaction. My teachers told me that in a zero order reaction, the rate of the reaction is independant of concentration of the reactants.

WebThe integrated rate law for the first-order reaction A → products is ln [A]_t = -kt + ln [A]_0. Because this equation has the form y = mx + b, a plot of the natural log of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k. Created by Jay. Sort by: WebFeb 2, 2024 · If changing the concentration of a reactant produces no change in rate, that reactant is said to be of the zeroth order. In this case, both reactants are of the zeroth order. Reacting two zeroth order reactions gives you an overall reaction order of zero. [10] 3 Determine the order of a reaction in which doubling one reactant quadruples the rate. WebA reaction order of -1 means the compound actually retards the rate of reaction.
