The kinetics of acetone hydrogenation on Pt catalysts has been studied by Sen and Vannice (See Problem 7.9) [35]. To determine which bonding mode is more probable, the heat of adsorption for an on-top ת1 μ2 adsorbed acetone species was compared to that for a di-s-bonded ת2 μ2 species which had a C atom and the O atom interacting with a close-packed Pt (111) surface. What are these two values? Which species is favored?
