At a particular temperature and [A]0 = 2.57 10-3 M, concentration versus time data were collected for this reaction, and a plot of 1/[A] versus time resulted in a straight line with a slope value of +3.89 10-2 L/mol · s.

(a) Determine the rate law, the intergrated rate law, and the value of the rate constant for this reaction.

Rate law

chemPadHelp

Rate = k[A]3

The equation described in your answer is not balanced.

Integrated rate law

1/[A] = kt + 1/[A]0

1/[B] = kt + 1/[B]0

[A]/kt = [B]

kt = [A]/[B]

Rate constant

L/mol · s

(b) Calculate the half-life for this reaction.
