34. r are widespread in the literature. This is so because usually both the frequency factor and the activation energy are determined by fitting an Arrhenius expression to the experimental TPD spectra. This procedure is questionable and subject to the compensation effect between the two quantities to be determined. A higher frequency factor produces a narrower TPD spectrum shifted to lower temperatures, which could be compensated by a higher value of the activation energy. In our simulations we have fixed the activation energy to a value which is close to those appearing in the literature, and we have adjusted the frequency factor in order to obtain the adequate wideness in the TPD spectra.
