Question
Determine the rate constant for this reaction if the temperature is raised to 100.0 °C, assume that the activation energy of this reaction equal the activation energy of step 1 in the mechanism.
1: Consider the following exothermic reaction at 25.0 °C:
(CH3);CBr (aq) + H2O (1) → (CH3)3COH (aq) + Br" (aq) + H* (aq)
The following mechanism was obtained for this reaction:
Step 1: (CH3);CBr → (CH3)3C* (aq) + Br" (aq)
Ea = 89.6 kJ/mol
Step 2: (CH3);C (aq) + H2O (1) → (CH3);COH,* (aq)
, Ea 60.3 kJ/mol
Step 3: (CH3);COH,* (aq) → H* (aq) + (CH3)3COH (aq)
Ea = 45.0 kJ/mol
