Use Biokin's DynaFit program. You will be able to fit any chemical model you want. http://www.biokin.com/dynafit/

As a general rule I'd try to avoid all those old linearization methods and fit the actual data. M. Kubala, J. Plásek, E. Amler, Eur. Biophys. J. 2003, 32, 363–369.

Thanks for your response.

I will check the program and will try to use.

Thank you so much Professor M. Eugenio Vazquez for that interesting program. It is really very helpful.

Dear Mostafa, I’m glad you like it. I discovered it a couple of years ago, and have found it really useful because you do not need to have an equation defining your model. Anyway, the credit should go to the author of the program ;-)
