Consider the following reaction:

$2NO_{2} + F_{2} \rightarrow 2NO_{2}F$

The above reaction is actually composed of two steps that take place at different rates:

1. $NO_{2} + F_{2} \rightarrow NO_{2}F + F$ (slow step)

2. $NO_{2} + F \rightarrow NO_{2}F$ (fast step)

Based on this, what is the rate law for the reaction?

The overall reaction can only proceed as quickly as the __________.
