... 1. Ideal combustion, resulting in only carbon dioxide and water, rarely happens. In general, at the very least, some carbon monoxide is also produced. The real combustion of methane is more closely represented, then, by the unbalanced equation CH4 + O2 H2O + CO2 + CO. If 0.100 mol CH4 is allowed t ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
