First-order reactions

WebAug 8, 2024 · The rate of a first-order reaction is proportional to the concentration of one reactant. A common example of a first-order reaction is radioactive decay, the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments. The rate law is: rate = k [A] (or B instead of A), with k having the units … WebAs with a first-order reaction, we can use integrated rate laws with experimental data of concentration and time over the course of a reaction to graphically determine the order and rate constant of a reaction. The integrated rate law can be rearranged to a standard linear equation format (y = mx + b, where m = slope and b = the y-intercept):

WebThe integrated rate law for the second-order reaction A → products is 1/ [A]_t = kt + 1/ [A]_0. Because this equation has the form y = mx + b, a plot of the inverse 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.

WebFor a first-order reaction, the half-life is given by: t1/2 = 0.693/k For a second-order reaction, the formula for the half-life of the reaction is: 1/k [R]0 Where, t 1/2 is the half-life of the reaction (unit: seconds) [R 0] is the initial reactant concentration (unit: mol.L -1 or M)

WebA first-order reaction depends on the concentration of only one reactant. As such, a first-order reaction is sometimes referred to as a unimolecular reaction.
