Question:
Le-Chatelier's principle is not applicable to
Le-Chatelier's principle is not applicable to
Show Hint
Le-Chatelier's principle is not applicable to pure solids and liquids because their concentrations do not change during chemical equilibrium.

- \({Fe}(s) + {S}(s) \rightleftharpoons {FeS}(s)\)
- \({N}_2(g) + 3 {H}_2(g) \rightleftharpoons 2 {NH}_3(g)\)
- \({N}_2(g) + {O}_2(g) \rightleftharpoons 2 {NO}(g)\)

The Correct Option is B
Solution and Explanation
Le-Chatelier's principle applies to systems where changes in temperature, pressure, or concentration cause a shift in equilibrium. However, it does not apply to pure solids and liquids, because their concentrations do not change significantly during a reaction.
Step 1: {Identifying the Pure Solids and Liquids}
In reaction (B), Fe and S are pure solids, and thus, their concentrations do not significantly change during the reaction. Therefore, Le-Chatelier's principle is not applicable here. Thus, the correct answer is (B).
