Heterogeneous recombination of nitrogen atoms by the Smith side tube method: Effects of tube length and homogeneous recombination

摘要

An apparent pressure dependence of the derived catalytic activity of Pyrex for recombination of nitrogen atoms was observed in a series of Smith side tube experiments. The pressure dependence is shown to arise from an improper application of the infinite cylinder approximation. The effect of homogeneous recombination on the modeling of Smith side tube experiments is explored numerically.
