Question

Quizplus · Accepted Answer

For a second-order reaction, the rate law is given by the equation $ \frac{1}{[A]} = kt + \frac{1}{[A]_0} $, where $[A]$ is the concentration of the reactant at time $t$, $k$ is the rate constant, and $[A]_0$ is the initial concentration. Plotting $1/[A]$ versus $t$ gives a straight line, indicating a second-order reaction.
