Why is it that when graphing first order reactions, it is either exponentially decaying or linear?

It changes based on whether it is integers or in ln form.

For first order reactions, the graph of the concentration of reactant vs time is exponentially decaying. However, a linear plot is obtained when graphing the natural log of the reactant concentration vs time.

the actual concentration of A in first order reactions is exponentially decaying; however, we plot the y axis using ln, which gives us a linear graph with a slope
