Step 1 Step 2 Step 3 Students in a SCH4U class were examining the reaction between 2-bromo-2-methlypropane and +H* (aq) water: + Br (aq) (CH3)3CBr (aq) + H₂O (1)→ (CH3)3COH Their rate experiments show that the reaction is first order in (CH3)3CBr, but zero order in water. One of the students, Yuek-Fen, presented the following rate mechanism to her class for the above reaction. Determine if the mechanism below is plausible. Explain how you arrived at your decision.
