When `NaNO_(3)` is heated in a closed vessel, oxygen is liberated and `NaNO_(2)` is left behind. At equilibrium

When NaNO_(3) is heated in a closed vessel, oxygen is liberated and NaNO_(3) is left behind. At equilibrium,

When NaCl_3 is heated in a closed vessel, oxygen is liberated and NaNO_2 is left behind. At equilibrium:

When NaNO_(3) is heated in a closed vessel, O_(2) is liberated and NaNO_(2) is left behind. At equilibrium: NaNO_(3(g)) hArr NaNO_(2(g)) + (1)/(2) O_(2(g))
