Unit of reaction kinetic rate

hi all
I am working on furnace simulation using fluent
I want to specify combustion reaction rate in "Species Transport" section on fluent.
Fluent give unit of activation energy (j/kmole) but unit of pre-exponential factor not specify and this caused to fluent solution diverge or reaction result not proper.
what is unit pre-exponential factor or how can i specify this?

Thanks,

Hello Esmaeil Jabbari,
In my work related to catalytic combustion process, I specified per-exponential factor in the unit of kmol/(m3.s)

:-)
