Webresponses. For a ﬁrst-order response, the steepest part of the slope is at the beginning, whereas for the second-order response the steepest part of the slope occurs later in the response. First- and second-order systems are not the only two types of system that exist. There are higher-order systems, such as third- or fourth-order systems. WebThese are what zero-order, first-order, and-second order reactions would look like if you had gathered data, used the integrated rate law, and thrown it into a graphing calculator. Notice that the slope of each of these graphs is the rate constant, k. But first and second-order look similar, and maybe we want to be extra careful.
