We are studying the following reaction. We make a plot of ln[A] vs. time as the reaction proceeds. This plot turns out to be linear with a slope of -0.25. What is the rate law expression for this reaction?

2 A → 3 B

• rate = -0.25 s^-1ln[A]

• rate = 0.25 s^-1 ln[A]

• rate = 0.25 M^-1s^-1 [A]

• rate = 0.25 s^-1 [A]
