WebMar 9, 2024 · This graph is referring to a first-order reaction. The plot of ln [A] vs. time is linear because first-order processes see the concentration of [A] undergo exponential decay; therefore, a graph of ln [A] for a first-order process would theoretically be linear with a slope=-k.

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. WebSep 7, 2024 · For a zeroth-order reaction, a plot of the concentration of any reactant versus time is a straight line with a slope of −k. For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of −k.
