Hi,

I want to simulate the pre-combustion in a combustion chamber in OpenFOAM.
With the program Gaseq I calculate the number of moles of the reactants and products:

3.053 C2H2 + 0.509 H2 + 28.888 O2 + 69.33 N2 -> 69.055 N2 + 3.55 H2O + 6.105 CO2 + 7.273e-04 CO + 20.72 O2 + 2.325e-02 OH + 8.165e-06 H + 1.361e-03 O + 1.022e-04 H2 + 0.549 NO

This reaction I will include in the chem.inp data in OpenFOAM. My problem is that I need the Arrhenius parameter for this reaction. How can I calculate the parameters A, b, Ea and the forward reaction orders.

Many thanks in advance.
