WebThe units of the rate constant, k, depend on the overall reaction order. The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and the units of k for a second-order reaction are 1/ (M·s). Created by Yuki Jung.

WebA first-order reaction is a chemical reaction where the reaction rate depends linearly on the reactant’s concentration. In other words, if the concentration is doubled, the reaction rate is also doubled. A first-order … WebThat means that that particular term disappears from the rate equation. The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2. We call this an overall second order reaction.

WebMar 8, 2024 · For a reactant to be considered first order, plotting the natural log against time (ln ( [A]) vs t) should result in a decreasing linear line. Finally, for a reactant to be considered second-order, plotting the inverse of its concentration (1/ [A] vs t) should result in an increasing linear line.

WebA first-order reaction can be defined as a chemical reaction in which the reaction rate is linearly dependent on the concentration of only one reactant. In other words, a first-order reaction is a chemical reaction in … WebYes, zero-order reactions have a half-life equation as well. We can derive it the same way we derive the half-life equations for the first and second-order reactions. The given integrated rate law of a zero-order reaction is: [A]t = -kt + [A]0. At half-life the concentration is half of its original amount, so [A]t = [A]0/2.
