Chapter 13, Problem 71RQ

At a certain temperature, the following data were collected for the reaction, ${\text{2ICl+H}}_{\text{2}}\to {\text{I}}_{\text{2}}+2\text{HCl}$:

Initial Concentrations $\left({\text{mol L}}^{\text{-1}}\right)$		Initial Rate of Formation of ${\text{l}}_{\text{2}}\left({\text{mol L}}^{\text{-1}}{\text{s}}^{\text{-1}}\right)$
$\left[\text{ICl}\right]$	$\left[{\text{H}}_{\text{2}}\right]$
0.12	0.12	0.0015
0.78	0.12	0.0098
0.12	0.089	0.0011

Determine the rate law and the rate constant (with correct units) for the reaction.
