For the elementary gas phase reaction H + C₂H4 -> C₂H5, the second-order rate constant, k,
varies with temperature in the following way:
(i)
(ii)
1/T
0.0050
0.0033
T/K
10¹2 k/cm³ molecule¹¹ s-¹
Use all the data to calculate the activation energy and the pre-exponential factor.
Using collision theory, determine a value for the reaction cross-section at 400 K.
