Transcribed Image Text: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 s-¹.
