JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Law of equilibrium and Equilibrium constant

  • question_answer
    For which of the following reactions does the equilibrium  constant depend on the units of concentration [AIIMS 1983]

    A)                 \[N{{O}_{(g)}}\] ⇌ \[\frac{1}{2}{{N}_{2(g)}}+\frac{1}{2}{{O}_{2(g)}}\]

    B)                 \[Z{{n}_{(s)}}+Cu_{(aq)}^{2+}\] ⇌ \[C{{u}_{(s)}}+Zn_{(aq)}^{2+}\]

    C)  \[{{C}_{2}}{{H}_{5}}O{{H}_{(l)}}+C{{H}_{3}}COO{{H}_{(l)}}\]⇌\[C{{H}_{3}}COO{{C}_{2}}{{H}_{5(l)}}+{{H}_{2}}{{O}_{(l)}}\] (Reaction carried in an inert solvent)

    D)                 \[COC{{l}_{2(g)}}\] ⇌ \[C{{O}_{(g)}}+C{{l}_{2\,(g)}}\]

    Correct Answer: D

    Solution :

           \[\Delta n\]= 1 for this change                                 So the equilibrium constant depends on the unit of concentration.
