Given the reaction at equilibrium: 2CO(g)+O 2 (g) leftrightarrow2CO 2 (g) Which statement regarding this reaction is always true? (A) The rates of the forward and reverse reactions are equal. (B) The reaction occurs in an open system (C) The masses of the reactants and products are equal (D) The concentrations of the reactants and products are equal .

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
