Question

A chemist proposes the following reaction mechanism:

Step 1: C2H5Br + AlBr3 → AlBr4 - + C2H5 +

Step 2: C2H5 + + C6H6 → C6H6C2H5 + (slow)

Step 3: C6H6C2H5 + + AlBr4 - → AlBr3 + HBr + C2H5C6H6

Write the overall reaction equation.

(b) List the reaction intermediate(s) and the catalyst. Intermediates: _______________________________ Catalyst: _________________

(d) A new catalyst is discovered that decreases the activation energy for step 3. How will this affect the overall rate of the reaction? Give a reason for your answer.

(e) The rate law equation was determined to be rate=k[C2H5 + ][C6H6] 2 . Is the proposed mechanism plausible? Support your answer.
