A survey of experimental and theoretical results concerning the thermodynamics and kinetics of surface chemical reactions of importance in late transition metal catalysis for energy technology will be presented.  Topics include:  (1) calorimetric measurements of the adsorption energies of small molecules and molecular fragments on single crystal surfaces, and their comparison to DFT results; (2) new ways to estimate prefactors in the rate constants for elementary steps in surface reactions based on experimental trends in adsorbate entropies, and (3) how to use these together with elementary-step rate measurements and/or DFT calculations to build microkinetic models for multi-step catalytic reactions.  Finally, we will discuss a method for analyzing such microkinetic models to quantify the extent to which each elementary step and intermediate controls the net rate, and describe how one can use this to define key descriptors that can be used for computational searches to discover better catalyst materials.<br/>Work supported by NSF and DOE-OBES Chemical Sciences Division, and the DOE EFRC Inorganometallic Catalyst Design Center (ICDC).
