The reaction: (CHÀ)ÀCBr + OHÈd (CHÀ)ÀCOH + BrÈ in a certain solvent is first order with respect to OHÈ. 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 10Ê K with a y-intercept of 33.5. What is the numerical value of the frequency factor, A?

Answers:
a) 33.5
b) 3.54 X 10 ^14
c) 1.10 X 10 ^4
d) 3.51
