    When sulphur is heated at \[\text{C}{{\text{u}}^{\text{2}+}}\] is converted into \[\text{C}{{\text{d}}^{\text{2}+}}\]. What will be the equilibrium constant for the reaction if initial pressure of 1 atm falls by 25% at equilibrium?

    A) \[\left( \text{Z}=\text{23} \right)\]                         

    B) \[HCl\]

    C) \[\text{BeO}\]                 

    D) \[\text{Ba}{{\text{O}}_{\text{2}}}\]

    Correct Answer: D

    Solution :

    \[C{{F}_{2}}C{{l}_{2}}\xrightarrow{hv}\overset{\bullet }{\mathop{Cl}}\,+C{{F}_{2}}\overset{\bullet }{\mathop{Cl}}\,\] \[\overset{\bullet }{\mathop{Cl}}\,+{{O}_{3}}\xrightarrow{{}}Cl\overset{\bullet }{\mathop{O}}\,+{{O}_{2}}\] At equalibrium \[Cl\overset{\bullet }{\mathop{O}}\,+O\xrightarrow{{}}\overset{\bullet }{\mathop{Cl}}\,+{{O}_{2}}\] Now.\[\Delta n=1-2=-1\]
