Q.30 Consider the reaction H2 + C2H4 → C2H6 The molecular diameters of H2 and C,H4 are 1.8 Å and 3.6 Å respectively. The pre-exponential factor in the rate constant calculated using collision theory in m (mole)sis approximately 8k„T 7 (For this reaction at 300 K, N =1.11x107 m(mole) s', where the symbols have their usual meanings) (A) 2.5x10 (B) 2.5x1014 (C) 9.4×10'7 (D) 9.4×1023 Q.30 Consider the reaction H2 + C2H4 → C2H6 The molecular diameters of H2 and C,H4 are 1.8 Å and 3.6 Å respectively.
