The reaction of 1-chlorobutane with a boiling sodium hydroxide solution is a two-phase reaction.  When the two-phase reaction is completed, why does a homogenous solution result?    

The reaction of benzyl bromide (C6H5CH2Br) with azide ion (N3-) is shown below.  When the benzyl bromide concentration is doubled and azide concentration is held constant, the reaction rate is observed to increase by a factor of two.  When the azide concentration is doubled and the benzyl bromide concentration is held constant, the rate of the reaction doubles.  What is the correct rate law for this reaction?                                                C6H5CH2Br  +  N3- ——>  C6H5CH2N3  +  Br- I.   Rate = k [C6H5CH2Br ]2 [N3- ]2 II.  Rate = k [C6H5CH2Br ]2 [N3- ] III. Rate = k [C6H5CH2Br ]4 [N3- ]2 IV. Rate = k [C6H5CH2Br ] [N3- ]
