WebA reaction has a half-life of 1 min. The time required for 99.9% completion of the reaction is 10 min. Explanation: This question is incomplete, order is not given. If we consider, the given reaction to be first order, then `"t"_(1//2) = (ln 2)/"k" => "k"` = ln 2 `therefore "t" = 1/"k" ln 100/(100 - 99.9) => "t" = 1/(ln 2) ln 10^3` WebJan 30, 2024 · The 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.
