Quizplus · Accepted Answer

The slope of a plot of concentration [A] versus time for a reaction that is linear indicates a first-order reaction, where the rate of reaction is directly proportional to the concentration of reactant A. The slope of this line is equal to the negative of the rate constant (k), as the equation for a first-order reaction is ln[A] = -kt + ln[A]0, where [A] is the concentration of A at time t, k is the rate constant, and [A]0 is the initial concentration of A.
