Question
what is the rate law for the following SN1 reaction? please explain.
To determine the rate law of the SN1 reaction:
In a test tube, add 0.5 mL of 0.1 M 2-chloro-2-methylpropane in ethanol.
In another test tube, add 0.5 mL of 0.2 M 2-chloro-2-methylpropane in ethanol.
At the same time, add 1 mL of 0.1 M silver nitrate in ethanol to each of the test tubes.
Record observations and compare the reaction rates of the 2 tubes.
In a test tube, add 1 mL of 0.1 M silver nitrate in ethanol.
In another test tube, add 0.5 mL of 0.1 M silver nitrate in absolute ethanol and 0.5 mL of absolute ethanol.
At the same time, add 1mL of 0.1 M 2-chloro-2-methylpropane in ethanol to each test tube.
Explanation / Answer
The SN1 reaction depends on the concentration of substrate only.For the first part when the AgCl is added , the 0.5 mL of 0.2 M 2-chloro-2-methylpropane in ethanol will react faster as it has higher concentration and it will be two times greater as concentration is doubled.
In the secone one when alkyl halide is added , the second testtube 0.5 mL of 0.1 M silver nitrate in absolute ethanol and 0.5 mL of absolute ethanol will have less concentration than 1 mL of 0.1 M silver nitrate in ethanol so rate is low .
