Options:
  • A equal volumes of $\mathrm{N}_{2}$ and $\mathrm{H}_{2}$ are reacting.
  • B equal manes of $\mathrm{N}_{2}$ and $\mathrm{H}_{2}$ are reacting.
  • C the reaction has stopped.
  • D the same amount of ammonia is formed, as it is decomposed into $\mathrm{N}_{2}$ and $\mathrm{H}_{2}$.

The correct answer is: the same amount of ammonia is formed, as it is decomposed into $\mathrm{N}_{2}$ and $\mathrm{H}_{2}$.
Since, at equilibrium,
rate of forward reaction $=$ rate of backward reaction.
Therefore, in the chemical reaction,
$$
\mathrm{N}_{2}+3 \mathrm{H}_{2} \rightleftharpoons 2 \mathrm{NH}_{3}
$$
the same amount of ammonia is formed, as it is decomposed into $\mathrm{N}_{2}$ and $\mathrm{H}_{2}$.
