Le-Chateliers' principle is not applicable to

Le-Chateliers' principle is not applicable to

Options

  1. AH2(g)+\mathrm{H}_2(\mathrm{ g})+\mathrm{I}2(g)⇌2HI(g)_2(\mathrm{ g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g})
  2. BFe(s)+S(s)⇌FeS(s)\mathrm{Fe}(s)+\mathrm{S}(s) \rightleftharpoons \mathrm{FeS}(s)
  3. CN2(g)+3H2(g)⇌2NH3(g)\mathrm{N}_2(\mathrm{ g})+3 \mathrm{H}_2(\mathrm{ g}) \rightleftharpoons 2 \mathrm{NH}_3(\mathrm{ g})
  4. DN2(g)+O2(g)⇌2NO(g)\mathrm{N}_2(\mathrm{ g})+\mathrm{O}_2(\mathrm{ g}) \rightleftharpoons 2 \mathrm{NO}(\mathrm{g})

Correct answer

B. Fe(s)+S(s)⇌FeS(s)\mathrm{Fe}(s)+\mathrm{S}(s) \rightleftharpoons \mathrm{FeS}(s)

Step-by-step solution

Le-Chatelier principle is not applicable to pure solids and liquids because they experience negligible change in concentration during chemical equilibrium.
