NEET Chemistry SN1 & SN2 Reactions MCQ Question
Consider a reaction where tert-butyl bromide undergoes an SN1 reaction in a polar protic solvent. If the initial concentration of tert-butyl bromide is 0.1 M and the rate constant for the reaction is 0.02 s^-1, what is the rate of the reaction?
0.002 M/s
0.02 M/s
0.01 M/s
0.2 M/s
Correct Answer
Detailed Explanation
The rate of an SN1 reaction follows first-order kinetics and is given by rate = k[tert-butyl bromide]. Using the rate constant k = 0.02 s^-1 and [tert-butyl bromide] = 0.1 M, the rate is 0.02 s^-1 * 0.1 M = 0.002 M/s.
