Identify A and B from the following reaction NaNO_3⟶∆xA+yB

Q16 / 160 · AP EAMCET 2022 (04 Jul Shift 1) · Chemistry

Identify $A$ and $B$ from the following reaction
${NaNO}_{3} \overset{∆}{⟶} xA + yB$

Correct answer
A
${NaNO}_{2}, O_{2}$
B
${Na}_{2} O, {NO}_{2}$
C
${Na}_{2} O, NO$
D
$Na, {NO}_{2}$

Solution

Almost all nitrates liberates the nitrogen dioxide gas on heating. But alkali metal nitrates liberates oxygen gas on heating except lithium nitrate. Hence, sodium nitrate gives sodium nitrite and oxygen gas.
${NaNO}_{3} \overset{∆}{\to} {NaNO}_{2} + \frac{1}{2} O_{2}$

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