First-order reactions

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): WebDeriving the integrated rate law for first-order reactions using calculus.

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.
