Problem

A

, the following half-life data are collected: •

[A]_0 = 0.50\,\text{M}

t_{1/2} = 120\,\text{s}

•

[A]_0 = 0.25\,\text{M}

t_{1/2} = 60\,\text{s}

(1) Identify the reaction order with respect to

A

. (2) Calculate the rate constant

k

, including correct units, using either data pair.
