KINETICS OF PHOTOCHEMICAL DECOMPOSITION OF SOLIDS (I)

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.
