✦ Synopsis

The coadsorption of C,H, with Hz and CO on Pd(ll1) has been investigated at 300 and 330 K_ At 300 2; two forms of adsorbed ethylene coexist on the surface in the presence of ethylene gas: a molecular iorm desorbing 3s C2 & at 330 K and a dissociatively adsorbed form (giving only hydrogen in dcsorption spectra) which is stable both in Mcmml and in hydrogen at lo-* Torr. The molecular form seems to be a precursor state for hydrogenation and for dissociative adsorption_ Both processes are controlled by the amount of coadsorbed hydrogen which in turn is controlled by CO coverage_

The reaction of C2H 4 on Pt{111} at 300 K has been investigated by single crystal adsorption calorimetry. The initial heats of adsorption and the initial sticking probability are 174 kJ/mol and 0.67 respectively. The adsorption heat versus coverage data shows a remarkable minimum which serves as a b
