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.

Web1. A = 100%, x = 20%, Therefore, a – x = 100 – 20 = 80 For the zero order reaction k = x t ( x t) ⇒ k = ( 20 20) = 1 Rate constant for a reaction = 1 2. To calculate the time for 80% of completion k = 1, a = 100, x = 80%, t = ? Therefore, t = x k ( x k) = ( 80 1) = 80 min Concept: The Integrated Rate Equation WebThe concentrations of reactant A at three different time intervals are given. Use the following data to determine the average rate of reaction in terms of the disappearance of reactant A between time = 0 s and time = 20 s. Time (s) 0 20 40. [A] (M) 0.0400 0.0240 0.0180.
