Abstract : The theoretical analysis of a transient method is presented for the quantitative study of heterogeneous reaction rates and gaseous, multi-component diffusion coefficients. From observations of the rate of decay of reactant after its source of supply has been shut off, the kinetics of chemical reaction on the catalytic surface may be obtained. Combined with steady-state measurements, the diffusional transport of reactant to the catalyst may be evaluated. This experimental approach is particularly applicable to systems involving highly reactive species such as free radicals and atoms. (Author)
