A plastic container is marked so that it can hold one part of methane, and two parts of oxygen. The container is then filled by displacing water by the stoichiometrically correct amounts of gases for the combustion of methane. At room temperature, no reaction appears to take place between these gases. Just because the system is not changing does not mean the reaction is at equilibrium. If we raise the temperature, the reaction takes place extremely rapidly. The reaction was not at equilibrium, it was just too slow at room temperature to notice that it was changing.
