Question
Consider the reactionH2 + C2H4 → C2H6 The molecular diameters of H2 and C2H4 are 1.8 Å and 3.6 Å respectively. The pre-exponential factor in the rate constant calculated using collision theory in m3 (mole)-1 s-1 is approximately (For this reaction at 300 K, [(8kbT)/πμ]1/2 NA = 1.11 * 1027 m(mole)-1 s-1, where the symbols have their usual meanings)
