Abstract:

It is shown that a common and valid approximation for the rate of unimolecular reaction at high temperatures may lead to error if applied to the calculation of the activation energy. This is most serious when data are extrapolated over a long temperature inverval, as is the case quite often in shock tube studies of unimolecular gas reactions and energy transfer efficiency. Correct expressions are formulated for various cases. Author
