WebFeb 12, 2024 · Since this is a zero-order reaction, the half-life is dependent on the concentration. In this instance, the half-life is decreased when the original concentration is reduced to 1.0 M. The new half-life is 80 seconds. Reaction B represents a zero-order reaction because the units are in M/s. WebApr 9, 2024 · The rate constant of a second-order equation expressed in integrated form is. 1 [ R] t − 1 [ R] o = k t. Since at half-life, the concentration of the reactant reduces to half, t = t1/2 (Half-life) and R = R o/2, the above equation becomes. 1 [ R] 0 2 − 1 [ R] o = k t 1 / 2. By rearranging the terms of the above equation, the half-life of a ...

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. Web12.
