Pre Exponential Factor for Carbon reactions

December 3, 2007, 01:12

Hello Fellows,

I am working on reaction of carbon with hot air, i m using C+O2-> CO2 C+CO2->2CO CO+0.5O2->CO2

Can any one provide me pre-exponential factor ( kgmol/m^3.s) and activation energy (j/kmol). As Pre-expoential factors mentioned n literature has different unit!! i will be thankful, if anyone help me in this regard. Thanking you!

the units of c + O2 == CO2 is (kg/m2sPa)

for CO reaction CO gas phase oxidation (Guo et al., 2003) Aco (m3/kg.s ) Eco(J/kmol) 3.13Ã-104 6.651Ã-107

convert kg to kmol
