I learned about the equilibrium constant. Now, I've seen that the equilibrium constant of burning is extremely small $(K \ll 1)$. here, I have a question. you see, $K$ is still NOT 0, which means that the forward reactions happen at least a tiny bit. Then, shouldn't we see some parts of anything burning at least a little bit?
Even if the concentration of product is extremely low compared to the reactants, shouldn't we observe something? Am I missing something?

Comment: The fact that there will always be some small reaction happening doesn't mean that you will see it or be able to detect it. The equilibrium constant $K$ is the ratio of the reaction rates of the forward and reverse reactions under equilibrium conditions. In the case of reactions with $K \ll 1$, the reverse reaction is much faster
Why is it that when I use a lighter, for instance, that things don't catch fire spontaneously all around me? Shouldn't the equilibrium constant $K$ for the carbon combustion be big enough for that to occur? I was told that I could calculate the amount of fuel needed for a car engine, assuming that everything burns completely and at constant pressure, knowing $H$ (enthalpy of combustion) and $K$ and by
