(D) The rate of an $S_N2$ reaction is given by the rate law: $Rate = k[Substrate][Nucleophile]$.$1$. The nucleophile: The strength and concentration of the nucleophile directly affect the rate.$2$. The carbon skeleton: Steric hindrance plays a crucial role; primary alkyl halides react fastest due to less crowding.$3$. The leaving group: $A$ better leaving group (weaker base) increases the rate of reaction.Therefore,all these factors influence the rate of $S_N2$ reactions.
