WebJun 20, 2024 · The half-life for 3rd order reaction is. t 1/2 = By plotting a graph between t 1/2 on the y-axis and on the x-axis if a straight line is obtained the reaction is third order. Graph. Mathematical method. The half-life for 1st order reaction, t 1/2 ∝. The half-life for 2nd order reaction, t 1/2 ∝. The half-life for 3rd order reaction, t 1/2 ∝ 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.
