Abstract
Hydrogenation and H-D exchange reactions of ethylene on 1 ML (monolaye r) Fe thin film with preadsorbed atomic hydrogen proceed through the f ormation of ethyl species and the products of ethylene and ethane show the incorporation of preadsorbed H or D atoms. beta-H elimination ste p of ethyl species exhibits a kinetic isotope effect; C-H cleavage is faster than C-D cleavage. The obtained bonding energy of ethyl species on 1 ML Fe film with adsorbed atomic hydrogen is (132 +/- 19) kJ/mol.
