Fatu %J Analele Universitatii Bucuresti : Chimie %D 2002 %I %X A model which describes the kinetics of photochemical decomposition:(S) (S) (g) aA !bB cC(the reaction area being located near the reactant surface) is presented.The general rate equation is discussed for various ratios between the radiation absorptioncoefficients of the solids A and B. The curves (reaction rate, degree of conversion) have beencalculated using a program written in BASIC language. %U http://gw-chimie.math.unibuc.ro/anunivch/2002-1/AUBCh2002XI15361.pdf
