Yes. I've chosen methane-air as the mixture. But, nitrogen being inert, it's not included in the reactants. Of course, I added it later to see if there's any change. Initially there's no combustion with the same conditions that were used without nitrogen. Later, I patched a fraction of products along with temperature, and this time there is combustion. But, as I mentioned earlier, the temperature raises to 500 K and starts decreasing after a few iterations.
