A mixture of 1-pentanol, concentrated hydrobromic acid, and sulfuric acid produces 1-bromopentane. This reaction follows a SN2 reaction mechanism. Consider the effect of running the same reaction again using twice as much solvent. In other words, the new concentration of 1-pentanol and hydrobromic acid would each be nearly halved. How would the two reaction rates compare?
The reaction rate for the dilute mixture would be one-fourth of that corresponding to the original mixture.
