How does doubling the concentration of both the alkyl halide and the nucleophile affect the rate of the above S N1 reaction?
Homework Answers
SN1 reaction rate only depends on the concentration of the alkyl halide as in the slow step the carbocation formation occurs. The rate is unimoecular or first order in the alkyl halide.
So, doubling the concentration of alkyl halide will increase the rate 2 times but doubling the concentration of nucleophile will not affect the rate.
