Hi,

in a well known 1-step reaction-mechanism from Westbrook and Dryer
(SIMPLIFIED REACTION MECHANISMS FOR THE OXIDATION OF HYDROCARBON FUELS
IN FLAMES, DOI: 10.1080/00102208108946970) i found a negative
reaction order for methane. When I try with

reaction( "CH4 + 2 O2 => CO2 + 2 H2O", [8.30000E+012, 0, 30],
order = " CH4:-0.3 O2:1.3")

in the cti-file I get:

Error: reaction order must be non-negative

Is it possible to bring such a reaction with into cantera?

best regards
ulf

P.S. looking forward to cantera-2.0 :)
