In the given reaction \({N_2} + {O_2}\) \(\rightleftharpoons\) \(2NO\), equilibrium means that
1 Concentration of reactants is changing where as concentration of products is constant
2 Concentration of all substances is constant
3 Concentration of reactants is constant where as concentration of products is changing
4 Concentration of all substances is changing
Explanation:
\(N _2+ O _2 \rightleftharpoons 2 NO\) Equilibrium is the point where concentration of all substances are constant, but reaction occurs in both direction to maintain constant concentration.

All reactions which have chemical disintegration
1 Is reversible
2 Is reversible and endothermic
3 Is exothermic
4 Is reversible or irreversible and endothermic or exothermic
Explanation:
Chemical disintegration is a method by which a compound gets broken down into two or more simpler molecules or atoms. All reactions which have chemical disintegration are reversible or irreversible and endothermic or exothermic. Example of irreversible and exothermic reaction which disintegrates into its following constituents: \(2 KClO _3( S ) \stackrel{\Delta}{\rightarrow} 2 KCl ( S )+3 O _2( g )\) Example of reversible reaction: \(N _2( g )+3 H _2( g ) \rightleftharpoons 2 NH _3( g )\) Example of endothermic reaction: \(HCO _3^{-}+ H ^{+} \rightarrow H _2 O + CO _2\)
Chemical Equilibrium

Amongst the following chemical reactions the irreversible reaction is
\(H _2+ I _2 \rightleftharpoons 2 HI\), this reaction is reversible, if it is carried out in a close container as all are in gaseous phase. \(CaCO _3 \rightleftharpoons CaO + CO _2\) is reversible as the activation energy ( \(Ea\) ) for backward reaction is not high. \(O _2+ SO _2 \rightleftharpoons 2 SO _3\) is also reversible in closed container as it is a gaseous phase reaction. \(Ag NO _3+ NaCl \longrightarrow AgCl + NaNO _3\) is irreversible as a precipitate is formed and backward reaction is not fearable. Option \(B\) is correct.
Chemical Equilibrium
