| Abstract: | Studies of water vapor adsorption on polycrystalline Rh at T>315 K and P=(2–4)×10–2 Pa indicate that water is adsorbed dissociatively to Oads and Oads through a molecularly adsorbed species. Desorption activation energy is 46 and 69 kJ/mol for molecular and dissociative species, respectively.
