R. Atkinson (J. Phys. Chem. Ref. Data 26, 215 (1997)) has reviewed a large set of rate constants relevant to the atmospheric chemistry of volatile organic compounds. The recommended rate constant for the bimolecular reaction of O2 with an alkyl radical R at 298 K is 4.7 × 109 dm3 mol−1 s−1for R = C2H5 and 8.4 × 109 dm3 mol−1 s−1 for R = cyclohexyl. Assuming no energy barrier, compute the steric factor, P, for each reaction. Hint: Obtain collision diameters from collision cross-sections of similar molecules in the Resource section.

R. Atkinson (J. Phys. Chem. Ref. Data 26, 215 (1997)) has reviewed a large set of rate constants relevant to the atmospheric chemistry of volatile organic compounds. The recommended rate constant for the bimolecular reaction of O₂ with an alkyl radical R at 298 K is 4.7 × 10⁹ dm³ mol⁻¹ s⁻¹for R = C₂H₅ and 8.4 × 10⁹ dm³ mol⁻¹ s⁻¹ for R = cyclohexyl. Assuming no energy barrier, compute the steric factor, P, for each reaction. Hint: Obtain collision diameters from collision cross-sections of similar molecules in the Resource section.
