When

{NaNO}_3

is heated in a closed vessel, oxygen is liberated and

{NaNO}_2

is left behind, then which of the following statements is correct at equilibrium?

{NaNO}_3({~s}) \rightleftharpoons {NaNO}_2({~s})+\frac{1}{2} {O}_2({~g}), \Delta {H}=+{ve}

View answer and explanation

Correct option: C

Increase in temperature favours forward reaction

Option C is correct because the reaction is endothermic (

\Delta H = +ve

), so increasing the temperature favors the forward reaction according to Le Chatelier's principle.
