The reaction (CH3)3 CBR+ OH------)(CH3)3 COH+Br in a certain solvent is first order with respect to (CH3)3 CBr 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 of -1.10x10^4 K and y-intercept of 33.5. Assume k has units 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 25 degrees C
