Regarding the unit of the kinetic pre-exponential factor k
Thread Content
I’m seeking help from experts. When performing reactive distillation, I obtained an pre-exponential factor with units of the reciprocal of time based on the reactions in the high-pressure reactor. Should I enter this value directly into Aspen? I’d appreciate it if experts could explain the units of the pre-exponential factor in the Arrhenius equation and those used in Aspen; I’m really confused.
Check the help directly; it’s explained clearly there!
The unit of the pre-exponential factor is related either to the unit of the activation energy E or to the choice of the rate reference and concentration reference for the system; this becomes clear upon further consideration.
If nothing else works, consider performing the conversion based on the units of the existing equations
