The decomposition of dinitrogen tetroxide (N2O4\text{N}_2\text{O}_4N2O4) into nitrogen dioxide (NO2\text{NO}_2NO2) is a reversible reaction that can reach a state of dynamic equilibrium.
N2O4(g)⇌2NO2(g) \text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\text{NO}_2\text{(g)} N2O4(g)⇌2NO2(g)The forward reaction is endothermic (absorbs heat).
Explain how the position of equilibrium changes if the temperature of the reaction mixture is decreased.
