When NaNO3 is heated in a closed vessel, oxygen is liberated and NaNO2 is left behind At equilibrium,

Question

When NaNO3 is heated in a closed vessel, oxygen is liberated and NaNO2 is left behind At equilibrium, (A) addition of NaNO2 favours reverse reaction (B) addition of NaNO3 favours forward reaction (C) increasing temperature favours forward reaction (D) increasing pressure favours reverse reaction

NaNO3 ( s) leftharpoons NaNO2 (s) + (1/2) O2 ( g), triangle H > 0 NaNO3 and NaNO2 are in so lid state, changing their amount has no effect on equilibrium . Increasing temperature will favour forward reaction due to endothermic nature of reaction. Also, increasing pressure will favour backward reaction in which some O2(g ) will combine with NaNO2 ( s) forming NaCO3
