Hi- in reactingFoam is the file constant/reactions. There is a list called "reactions" and in parentheses there are three numbers (5.2e16 0 14906). Anybody know what these are? Thanks!

Thank you Mahdi! So 5.2e16 is the pre-exponential factor "A", and 14906 is the activation energy in J/mol, correct? But what is the zero in the middle? Thanx again -Scot

niklas will become famous soon enough
The numbers are (A n Ea)

where
k = A*T^n*exp(-Ea/(R*T))
