Question 16

Nitrogen dioxide gas reacts to form dinitrogen tetroxide gas. Nitrogen dioxide is a brown gas and dinitrogen tetroxide is a colourless gas.

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

Nitrogen dioxide is sealed in a container and left until a state of dynamic equilibrium is reached.

The conditions are then altered to favour the forward reaction.

Explain what you would observe as the mixture reaches its new equilibrium.
