Chapter 20, Problem 20.11E

Rate law experiments don’t always give data in the form of a rate in moles per second. Some of them give an amount of time necessary for a reaction to proceed to a given point. The faster the rate, the less time necessary. For the following data, assume that the time given is to react $0.10\text{M}$ of $\text{A}$. Determining the complete rate law for the reaction $\text{A}+\text{B}\to \text{products}$.

Time taken $\left(s\right)$	$\left[A\right]$	$\left[B\right]$
$36.8$	$0.20$	$0.40$
$25.0$	$0.20$	$0.60$
$10.0$	$0.50$	$0.60$

(A classic chemical reaction/demonstration called the iodine clock reaction is usually measured this way.)
