  I am trying to simulate biomass combustion in ansys fluent. I have a second order combustion reaction. I was wondering what will be the value of the pre-exponential factor of the arrhenius rate. I do not know the exact unit of pre-exponential factor ansys fluent is using but i know that 2nd order reactions have pre-exponential factor molL^-1s^-1. I would really appreciate it if anyone can help. Thanks

  Note, "kg mol" is kmol in American. Why they need to be different is an entirely different question.....
