It is a primary halide will undergo SN2 mechanism.
The rate of the reaction will depends upon both concentration of nucleophile as well as alkyl halide

Suppose you have a following reaction: How does the reaction rate change increase, decrease, does not change) if you: a) increase the concentration of sodium iodide twice b) use n-hexane as a solvent instead of acetone c) use 2-bromopropane as electrophile instead of bromoethane d) use two times higher volume of solvent (keeping the amount of both alkyl bromide and sodium iodide the same). In each case use one-two sentences to justify your answers CH3CH3Br + Nal acetone → CH2CH3...
