reduced mechanism

A. Belcadi

I'm a Phd student in my final year and I hope to get help through this user forum. I determined the reduced mechanisms but i found several difficulties for the validation of these reduced mechanisms with the detailed mechanism.I work by Chemkin subroutines. my questions are as follows: 1- which are the modifications which I must make in subroutine CKWYP? 2- what is the mathematical relation used by Pr J Chen for determing the inverses constants of the reactions in the mechanisms detailed? if there are documentations concerning the two questions, please tries to send them on my email(abdobel@hayoo.fr). thank you very much for the assistance that you will dennerez me to carry out this task.
