Question 10

When dinitrogen tetroxide gas (N2O4{\text{N}_2\text{O}_4}N2​O4​) is heated in a sealed tube, it decomposes to form brown nitrogen dioxide gas (NO2{\text{NO}_2}NO2​).

Eventually, this reversible reaction reaches a state of dynamic equilibrium:

N2O4(g)⇌2NO2(g) \text{N}_2\text{O}_4(\text{g}) \rightleftharpoons 2\text{NO}_2(\text{g}) N2​O4​(g)⇌2NO2​(g)

State what is meant by the term dynamic in this context.
