Hello, researcher. I am making a MFIX-GCP model with chemical reactions. For a reaction, its pre-exponential factor A is 17 m/s, the activation energy is 69488 J/mol, and the reaction heat is −2760 J/mol. My settings in the model are as follows, is it correct？

This is my file. I set up a total of six reactions. Taking the first reaction as an example, its pre-exponential factor is 23.57m/s, the activation energy is 50.2 kJ/mol, and the reaction heat is-2.76 kJ/mol. How should I fill in these values in the software, in other words, how to convert the units of these parameters.
It looks to me like you have set these correctly. If you know the energies in kJ/mol and want to convert to j/kmol, multiplying by 1e6 is correct. Are you seeing reasonable results with this simulation?
At present, the reaction is successful, but whether the specific results are reasonable remains to be verified.
