Halogen compounds — practice question

Halogenoalkanes are used in many chemical applications, especially as intermediates in organic reactions. The three reactions of 1-bromobutane, $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{Br}$, are illustrated.
(a)[6]

State the reagent and the solvent for reaction 1, reaction 2 and reaction 3.

(b)[3]

If 1-iodobutane, $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{I}$, is treated under the same conditions as in reaction 1, butan-1-ol is produced. Compared with the reaction of 1-bromobutane, what, if any, change would there be in the rate? Explain your answer using suitable Data Booklet data.
