Assertion : Pure $\mathrm{N}_2$ is formed from $\mathrm{Ba}\left(\mathrm{N}_3\right)_2$. Reason : Thermal decomposition of $\mathrm{NaN}_3$ is used to inflate the air bags used for safety devices in some cars.
  1. If both assertion and reason are true and reason is the correct explanation of assertion.
  2. If both assertion and reason are true but reason is not the correct explanation of assertion.
  3. If assertion is true but reason is false.
  4. If both assertion and reason are false.

Solution

Correct explanation: \(\mathrm{Ba}\left(N_3\right)_2\) upon thermal decomposition gives pure \(N_2\).
\(\mathrm{Ba}\left(N_3\right)_2 \xrightarrow{\text { heat }} \mathrm{Ba}+3 \mathrm{~N}_2\)
