Question

For the fictitious reaction:  AB → A + B

Some data was collected measuring the [AB] at certain time intervals.  This data was then graphed as described below.

A graph of 1/[AB] versus time (s) gives a straight line with the equation: y = 0.0052x + 0.1135 and a R2 = 0.9995.  A graph of ln[AB] versus time (s) gives a straight line with the equation: y = -0.0068x + 1.725 and a R2 = 0.8925.   Assume the data doesn't fit a zero order reaction.

The rate law is: Rate = k[AB]2

Find:

What is the value of the rate constant for the given reaction?

Select one:
a. k = 0.0157 Ms-1
b. k = 0.0052 M-1s-1
c. k = 0.0068 s-1
d. There is no way to determine the value of the rate constant from the given information.
