A survey of results concerning the thermodynamics and kinetics of surface chemical reactions of importance in late transition metal catalysis will be presented.  Topics include:  (1) microcalorimetry studies of adsorption energies of small molecules on metal single crystal surfaces and on size-defined metal nanoparticles supported on oxide single crystals, with comparisons to theoretical results by DFT; (2) trends in ligand-metal bond energies at the Pt(111) surfaces and their correlation with the corresponding hydrogen�ligand bond energies in gas-phase molecules, and (3) using these together with elementary-step rate measurements to build microkinetic models for multi-step catalytic reactions, and (4) methods for analyzing such microkinetic models that quantify the extent to which each elementary step and intermediate controls the net rate.      Work supported by NSF and DOE-OBES Chemical Sciences Division.
