Q19 / 160 · TS EAMCET 2015 · Chemistry

Ammonia on reaction with chlorine forms an explosive $\mathrm{NCl}_3$. What is the mole ratio of $\mathrm{NH}_3$ and $\mathrm{Cl}_2$ required for this reaction?

  • A
    $8: 3$
  • B
    $1: 1$
  • Correct answer
    C
    $1: 3$
  • D
    $10: 1$

Solution

The balanced equation is $$ \mathrm{NH}_3+3 \mathrm{Cl}_2 \longrightarrow \mathrm{NCl}_3+3 \mathrm{HCl} $$ Thus, the ratio of $\mathrm{NH}_3$ to $3 \mathrm{Cl}_2$ is $1: 3$.

Hence, the correct answer is option: 'C'.
