Correct explanation: B a(N3)2 upon thermal decomposition gives pure N2. B a(N3)2 xrightarrow text heat B a+3 N2

Q. Assertion : Pure $N_{2}$ is formed from $B a (N_{3})_{2}$ .
Reason : Thermal decomposition of $N a N_{3}$ is used to inflate the air bags used for safety devices in some cars.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Correct explanation: $B a (N_{3})_{2}$ upon thermal decomposition gives pure $N_{2}$ .
$B a (N_{3})_{2} heat B a + 3 N_{2}$
