First-order … WebA slower reaction will have a longer half-life, while a faster reaction will have a shorter half-life. To determine the half-life of a first-order reaction, we can manipulate the integrated rate law by substituting t 1/2 for t and [A] t1/2 = [A] 0 for [A] t, then solve for t 1/2: ln = –kt + ln (integrated rate law for a first-order reaction)
WebRate laws describe the progress of the reaction; they are mathematical expressions which describe the ... The half–life is defined as the time it takes for half of the initial amount of reactant to disappear (i.e. a reduction of 50% its original amount). If we replace this idea on the integrated rate law we get: 1 2 [ ]0=− G P1 WebJan 26, 2015 · In this video, we'll use the first-order integrated rate law to calculate the concentration of a reactant after a given amount of time. We'll also calculate the amount of time it takes for the …
