Question:

The reaction (CH3)3CBr + OH- → (CH3)3COH + Br2 in a certain solvent is first order with respect to (CH3)3CBr and zero order with respect to OH-. In several experiments the rate constant k was determined at different temperatures. A plot of ln(k) versus 1/T was constructed that resulted in a straight line with a slope of 21.10 × 104 K and a y intercept of 33.5. Assume that k has units of s-1.
a. Determine the activation energy for this reaction.
b. Determine the value of the frequency factor A.
c. Calculate the value of k at 25oC.
