The activity of a catalyst has been explained in terms of spontaneous adsorption of reactant moleculse on the surface of catlyst and ther by forming an activated adsorbed complex along with evolution of heat. The adorbed activated complex undergoes to decompositio to regencerate catlyst and give products . adorpton is of two types :
(i) Physical adsorptio due to van der Waal's forces of attraction between reactant and catalyst molecules , weak , less exothermic, mulitlay and non-dirctional .
(ii) Chemical dasorpton due to free valencies , strong, more exothermic, unilayer. The extent of adormpotion `( x//m)` vs temperature at constant pressure gives isobars. Freundilish studied influence of pressure on the phusical adorptons and reported that log `x/m log K + 1/n log P`.
The extent of adsroptong depends on :
