WebHalf-life The half-life of a reaction is the amount of time it takes for it to become half its quantity. Half-Life of a First-Order Reaction Recall that for a first-order reaction, the integrated rate law is given by: [A]= [A]_0 e^ {- (kt)} [A] = [A]0e−(kt) This can be written another way, equivalently: ln [A]=ln [A]_ {0}-kt ln[A] = ln[A]0 −kt 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 ...
