Problem 4: Determination of Pre-exponential Factor from Transition State Theory Consider the reaction between the methyl radicals to form ethane at 298 K. CH,+CH, CH The activated complex will be denoted C,H. You will assume high vibration frequency for both CH, and C.H. (hence, q' = 1). You will also assume no electronic degeneracy. a) Determine the translational, rotational, vibrational and electronic contributions for both CH, and CH'. Deduct the molecular partition function. b) Estimate the pre-exponential factor of the rate constant k from the transition state theory. c) Comparing the values of the pre-exponential factors obtained from both the transition state theory and the collision theory, determine the steric factor. Additional data: For CH: A=9.32 cm, B = = 14 cm o(symmetry number) = 3 For CH.": A = 4.66 cm, B =C = 2.80 cm (symmetry number) = 18 For the collision theory you will assume a collision cross section, o =0.46 nm
