The reaction: (CH3)3CBr + OH− → (CH3)3COH + Br− in a certain solvent is first order with respect to OH−. In several experiments, the rate constant k was determined at different temperatures. A plot of ln(k) vs 1/T was constructed and the slope of the line was -1.10 x 104 K with a y-intercept of 33.5. What is the activation energy for this reaction?
A) -91,400 J/mol
B) -1.10 × 10⁴ J/mol
C) 1.10 × 10⁴ J/mol
D) 91,400 J/mol
