Question

Question 8. The reaction (CH3)3CBr + OH---->(CH3)3COH + Br 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 In(k) versus 1/T was constructed resulting in a straight line with a slope value of -1.10 × 104 K and y-intercept of 33.5. Assume k has units of s¹. a. Determine the activation energy for this reaction. b. Determine the value of the frequency factor A. c. Calculate the value of k at 25°C.
