Question

What is the effect on the rate of doubling the amount of solvent and increasing the temperature by 20°C in an SN2 reaction? Assume all other variables in the reaction (other than the one(s) mentioned) remain constant.

a) 2 x rate

b) 1/4 the rate

c) Rate stays the same

d)1/2 the rate

e) 4 x rate

Answer 1

c) Rate stays the same

Step-by-step explanation:

SN2 reaction rate only depends on the substrate and nucleophile. Therefore, changing the solvent or temperature would have no effect on the rate.
