This question is about nitrogen oxides.

Dinitrogen tetroxide gas decomposes to form nitrogen dioxide gas. Nitrogen dioxide gas can also react back to form dinitrogen tetroxide gas.

a.

Which two words describe the reaction where dinitrogen tetroxide decomposes to form nitrogen dioxide?

  • Decomposition
  • Neutralisation
  • Precipitation
  • Polymerisation
  • Reversible
[2]
b.

The equation for the reaction is: N2O4(g)⇌2NO2(g)\text{N}_2\text{O}_4(\text{g}) \rightleftharpoons 2\text{NO}_2(\text{g})N2​O4​(g)⇌2NO2​(g)

Which statement describes this reaction at dynamic equilibrium?

  • The rate of the forward reaction is lower than the rate of the reverse reaction.
  • The rate of the forward reaction is equal to the rate of the reverse reaction.
  • The rate of the forward reaction is higher than the rate of the reverse reaction.
