The hydrogenation of ethylene (C2H4) to ethane (C2H6)is accomplished by the following mechanism:
(1) H2 <--> 2H
(2) C2H4 + H --> C2H5
(3) C2H5 + H --> C2H6
Net: H2 + C2H4 --> C2H6
Classify the reaction molecularity in each elementary step. If the overall rate expression for the net reaction is rate = k[H2], which elementary step is the rate determining step?
(A) Molecularity of a reaction step is the total number of reacting molecules in that step. Therefore, the molecularities ...
