The reaction of methyl iodide with sodium azide, NaN₃, proceeds by an S_N2 mechanism. What is the effect of doubling the concentration of NaN₃ on the rate of the reaction? A) the rate remains the same B) the rate decreases by a factor of 2 C) the rate increases by a factor of 2 D) the rate increases by a factor of 4

Question

Quizplus · Accepted Answer

In an SN2 mechanism, the rate of the reaction is directly proportional to the concentration of both the nucleophile and the substrate. Therefore, doubling the concentration of the nucleophile (NaN₃ in this case) would double the rate of the reaction.
