What volume of ammonia is formed when $10 \mathrm{dm}^3$ dinitrogen reacts with $30 \mathrm{dm}^3$ dihydrogen at same temperature and pressure?
  1. $30 \mathrm{dm}^3$
  2. $20 \mathrm{dm}^3$
  3. $15 \mathrm{dm}^3$
  4. $10 \mathrm{dm}^3$

Solution

$\begin{aligned} & \text { Nitrogen }_{(\mathrm{g})}+\text { Hydrogen }_{(\mathrm{g})} \longrightarrow \text { Ammonia }_{(\mathrm{g})} \\ & {[1 \mathrm{~L}] \quad[3 \mathrm{~L}] \quad[2 \mathrm{~L}]} \\ & {\left[10 \mathrm{dm}^3\right] \quad\left[30 \mathrm{dm}^3\right] \quad\left[20 \mathrm{dm}^3\right]} \\ & \end{aligned}$
