When the reaction A → B + C is studied,a plot of ln[A]t vs.time gives a straight line with a negative slope.What is the order of the reaction with respect to A?

Quizplus · Accepted Answer

If the plot of ln[A]t vs. time gives a straight line with a negative slope, this indicates that the reaction is first order with respect to A. This is because the integrated rate law for a first order reaction is:

ln[A]t = -kt + ln[A]0

where [A]t and [A]0 are the concentrations of A at time t and at t=0, respectively, k is the rate constant, and t is the reaction time. This equation describes a straight line with a negative slope when ln[A]t is plotted against time.
