# Predicting incomplete combustion?

I understand the concept of incomplete combustion and that it occurs when oxygen is not a large enough supply to allow for complete combustion. My question is: how can we model combustion properly in terms of predicting the ratio of complete to incomplete combustion? Is it possible to use basic kinetic with reaction rate constants to model the rate of each reaction and then obviously model how the changing concentration from both affects each individual rate etc.

• Very interesting question - I would be very interested if there has been a study based on this. – user15489 May 26 '15 at 10:45
• This sounds possible in principle, but quite hard in practice. Wonder if anyone has some good input on it. – Nicolau Saker Neto May 26 '15 at 11:27

Before entering the kinetics realm, it is advisable to check the equilibrium. Besides the straightforward combustion reactions, you have two more, Boudouard reaction, which favors formation of $\ce{CO}$ from $\ce{CO_2}$ and Water-gas shift reaction.
