Which statements about substitution reactions are correct?

I. The reaction between sodium hydroxide and 1-chloropentane predominantly follows an ${\mathrm{S}}_{\mathrm{N}}2$ mechanism.

II. The reaction between sodium hydroxide and 2-chloro-2-methylbutane predominantly follows an ${\mathrm{S}}_{\mathrm{N}}2$ mechanism.

III. The reaction of sodium hydroxide with 1-chloropentane occurs at a slower rate than with 1-bromopentane.
