Le-Chatelier’s principle is not applicable to

Q1 FREE PREVIEW

Le-Chatelier’s principle is not applicable to

a

\({H}_{2}(g)+{I}_{2}(g)⇌2HI(g)\)

b

\(Fe(s)+S(s)⇌FeS(s)\)

c

\({N}_{2}(g)+3{H}_{2}(g)⇌2N{H}_{3}(g)\)

d

\({N}_{2}(g)+{O}_{2}(g)⇌2NO(g)\)

✓ Correct answer: b)

\(Fe(s)+S(s)⇌FeS(s)\)

Explanation

Le-Chatelier’s principle applies to equilibrium involving gases or solutions. It is not applicable to Fe(s) + S(s) ⇌ FeS(s)as solids do not affect equilibrium. Correct answer: (B).
