By end product analysis
The authors do not specifically list rate parameters for this channel although it is the primary pathway (approximately 90% of reaction). Rate constants for this reaction were derived by us as the difference between those for the overall reaction [C6H5CH(OH)COOH -> PRODUCTS] and those given for the secondary channel [C6H5CH(OH)COOH -> C6H5CH2OH + CO2]. Rate parameters were then derived by us from a least squares analysis of these data.
Kinetics were determined by following pressure vs. time. Products were determined by GC product analysis.
Uncertainties are precision only and are at the 90% confidence level.
