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.

- \({H}_2(g) + {I}_2(g) \rightleftharpoons 2 {HI}(g)\)
- \({Fe}(s) + {S}(s) \rightleftharpoons {FeS}(s)\)
- \({N}_2(g) + 3 {H}_2(g) \rightleftharpoons 2 {NH}_3(g)\)
- \({N}_2(g) + {O}_2(g) \rightleftharpoons 2 {NO}(g)\)
Show Solution
The Correct Option is B
Solution and Explanation
Le Chatelier's principle dictates how equilibrium shifts in response to changes in temperature, pressure, or concentration. This principle, however, excludes pure solids and liquids due to their negligible concentration changes during reactions.
Step 1: {Identifying Pure Solids and Liquids}
In reaction (B), Fe and S are pure solids. Their concentrations remain largely constant throughout the reaction, rendering Le Chatelier's principle inapplicable. Consequently, option (B) is the correct choice.
