We’re given the plot of k (y) vs. 1/T (x).
This means we need to use the two-point form of the Arrhenius Equation:
m = slope
b = y-intercept
(CH3)3CBr + OH- → (CH3)3COH + Br-
in a certain solvent is first order with respect to (CH 3)3CBr and zero order with respect to OH 2. In several experiments, the rate constant k was determined at different temperatures. A plot of ln(k) versus 1/T was constructed resulting in a straight line with a slope value of -1.10 x 104 K and y-intercept of 33.5. Assume k has units of s-1.
a. Determine the activation energy for this reaction.
