The given chemisorption of hydrogen, H 2 follows the Langmuir isotherm with α = 3.67 k P a − 1 . The fractional surface coverage of hydrogen gas when the pressure is 20 P a has to be calculated. Concept introduction: Adsorption: A molecule (adsorbate) that forms a bond to the surface (adsorbent). Associative Adsorption: A gas molecule adsorbs without fragmentation. Dissociative Adsorption: A gas molecule adsorbs and fragmentation occurs. Langmuir adsorption: The isotherm is based on the characteristic assumptions that only monomolecular adsorption takes place, adsorption is localized and the heat of adsorption is independent. Langmuir equation: p / V = p / V m + a V m
