Key Concepts

Open vs Closed Systems

The distinction between open and closed systems is crucial when discussing equilibrium. In open systems, such as a gas burner, matter is continuously exchanged with the surroundings, which prevents the system from achieving a dynamic equilibrium that is characterized by fixed concentrations of reactants and products.

Reaction Irreversibility in Combustion

Many combustion reactions, like the burning of methane, are highly exothermic and tend to proceed nearly to completion. Due to the extreme energy release and the high activation energy required for the reverse reaction, the backward process is insignificant, meaning that a true equilibrium is not established under such conditions.

Chemical Equilibrium

Chemical equilibrium is the state in a reversible chemical reaction when the rates of the forward and reverse reactions are equal, leading to constant concentrations of all species involved. This concept is typically applicable in closed systems where no matter enters or leaves the system.
