  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

  Section 16.1.1.4.2 https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v231/en/flu_ug/flu_ug_chp_finrate.html
  Note, "kg mol" is kmol in American. Why they need to be different is an entirely different question.....
