Finite rate chemistry
 

Hello Every one,
I am accounting reactions with finite rate chemistry model. for calculating rate constant i am using arrhenius equation. I struck with the input units and then i refereed fluent theory guide. For SI unit system, whether the following units are correct for fluent input.
Activation energy = [J/k mol]
Temperature exponent = [dimensionless]
Gas constant (R) = [j/k mol]

Pre-exponential factor
1st order = 1/s
2nd order = m3/kg s

and what is the unit for 3rd order reaction.
