The hydrolsis of ( CH3 )3 CCI by OH ion proceed in two steps:Which of the following rate equation is consistent with this mechanism of reaction?
Correct answer: D. rate =k[RCI]
- A. rate =k[RCI]2
- B. rate =k[RCI] [OH-]2
- C. rate =k[RCI] [OH-1]
- D. rate =k[RCI]
Explanation
Step 1 (Rate-Determining Step):(CH3)3CCl → (CH3)3C+ + Cl-Step 2:(CH3)3C+ + OH- → (CH3)3COH.Option D proposes that the rate is proportional to the concentration of (CH3)3CCl. Considering the rate-determining step involves the formation of (CH3)3C+ from (CH3)3CCl, this option accurately reflects the slow step of the mechanism.Given the provided mechanism, the correct answer is: Correct Option: D) rate = k[RCI]

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
