Assuming no other changes, what is the effect of doubling only the concentration of the alkyl halide in the above SN2 reaction? A) no change
B) triples the rate
C) rate is halved
D) doubles the rate
E) quadruples the rate

D) doubles the rate

Explanation:

The given reaction is :

For the reaction, the rate of reaction depends upon the concentration of both the as well as the

That is the rate =

Now if the becomes , then the rate becomes double.

So the rate' is :

=

= 2 x rate

Therefore, the answer is (D) doubles the rate.

b
