Lindemann unimolecular fall-off in weak-collision systems at high temperature

The solution of the master equation for thermal unimolecular reactions predicts that (for weak-collision systems) the unimolecular reaction rate approaches the Lindemann fall-off behaviour at high temperature. The prediction is confirmed by experimental rate data for the decomposition reactions of hydrazine, carbon dioxide, nitrous oxide and nitrogen dioxide at shock wave temperatures. (Auth.)
