Question

Le-Chatelier's principle is not applicable to which of the following system?

• A. $P{Cl}_{5\left(g\right)}\rightleftharpoons P{Cl}_{3\left(g\right)}+{Cl}_{2\left(g\right)}$
• B. ${RCOOH}_{\left(l\right)}+R^{\prime }{OH}_{\left(l\right)}\rightleftharpoons {RCOO{R}^{\prime }}_{\left(l\right)}+H_2{O}_{\left(l\right)}$
• C. $C_{g\left(s\right)}\rightleftharpoons C_{d\left(s\right)}$
• D. All of these

Answer 1

Answer: (C)

$C_{g\left(s\right)}\rightleftharpoons C_{d\left(s\right)}$

Le-Chatelier's principle is not applicable to pure solids and liquids since they experience negligible change in concentration during chemical equillibrium. Hence C is correct
