✦ Synopsis

AM-Models mcorporatmg surface reactton and dttfuslon of volattle products through a boundary layer are developed to calculate effective rates of evaporation and local surface profiles on surfaces havmg active and InactIve resons The couphg between surface heterogeneities v&h respect to a particular reaction and external mass transfer may provide a mechatusm of the surface rearrangement and metal loss of catalysts encountered tn several systems of pracbcal mterest Calcufated transport rates for the volatthzatton of Pt m oxidtzmg envuonments and the rearrangement of tlus metal dunng the ammoma olt&ation reaction are found to agree weU with expcnmentai data -CTION
