Title: Energy transfer effects during the multichannel decomposition of ethanol
Journal: Inter. J. Chem. Kinet.
Volume: 36
Page(s): 456 - 465
Year: 2004
Reference type: Journal article
Squib: 2004TSA456-465
Reaction:
C2H5OH → C2H4 + H2O
Reaction order:
2
Temperature:
800 - 1800
K
Rate expression:
2.05x1012 [cm3/molecule s] (T/298 K)-17.90 e-354637 [J/mole]/RT
Category: Experiment
Data type:
RRK(M) extrapolation
Pressure dependence:
Rate constant is low pressure limit
Comments:
Results are based on a review and analysis of the literature data. The article discusses the multi-channel nature of ethanol decomposition and difficulties associated with expressing the rate constants in a convenient analytical form over extended temperature and pressure ranges.
Some analytical formats for intermediate pressures are also given in the paper but are too complex to reproduce here.
