WebHalf-life calculation on second order reactions results in concentration [A] vs. time (t), i.e., the length of half-life increases with the decrease of concentration of the substrate. The rate law of a second order reaction is: 1[A] = k × t + 1[A] 0----- (5) Determining half-life t/2 from the above equation: Web8 years ago. In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant).

WebJust as systems exhibiting exponential growth have a constant doubling time, systems exhibiting exponential decay have a constant half-life. To calculate the half-life, we want to know when the quantity reaches half its original size. Therefore, we have. y0 2 = y0e−kt 1 2 = e−kt − ln2 = −kt t = ln2 k. WebWe 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.
