What data should be plotted to show that experimental concentration data fits a first-order reaction?

Question

Quizplus · Accepted Answer

For a first-order reaction, the rate follows the equation: rate = k[A], where [A] is the concentration of reactant at a given time t, and k is the rate constant. Taking the natural logarithm of both sides of the equation results in ln(rate) = ln(k) + ln[A]. This can be rearranged to give a linear relationship between ln[A] and time: ln[A] = -kt + ln[A]0, where [A]0 is the initial concentration of reactant. Therefore, plotting ln[A] against time should result in a straight line with a negative slope, indicating that the data follows a first-order reaction.
