The second-order rate constants for the reaction of oxygen atoms with aromatic hydrocarbons have been measured (R. Atkinson and J.N. Pitts, J. Chem. Phys. 79, 295 (1975)). In the reaction with benzene, the rate constants are 1.44 x 10 ⁷ L/mol s at 300.0 K, 3.01 x 10 ⁷ L/mol s at 341.2 K, and 6.90 x 10 ⁷ L/mol s at 392.2 K.

a) What is the pre-exponential factor?

b) What is the activation energy?
