What is the slope of the linear plot of a first order reaction?

The slope of the first order reaction can be found through assessing the integrated rate law. The first order integrated rate law is ln(A)=-kt+ln(Ao), which is in the linear y=mx+b form. As such, the slope is -k.

The slope of the graph is -k. The graph is baed on ln(a) against time.

When you say linear plot of a first order reaction you are refering to the graph that results from a plot of ln[A] and time which results in a negative slope. However, if you were to graph [A] vs. time without the ln, you would not get a linear plot, instead a plot of exponential decay
