Integrated rate law of first order
NettetAs 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): NettetMathematically, this statement is expressed by the first-order differential equation, This equation is readily integrated to give. in which N is the number of atoms present when time equals zero. From the above two equations it may be seen that a disintegration rate, as well as the number of parent nuclei, falls exponentially with time.
