    Daltons law of partial pressure is not applicable to

    A)  \[{{O}_{2}}+{{O}_{3}}\]                

    B)  \[CO+C{{O}_{2}}\]

    C)  \[N{{H}_{3}}+HCl\]                        

    D)  \[I+{{O}_{2}}\]

    Correct Answer: C

    Solution :

                     Daltons law of partial pressure- This law states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of partial pressure exerted by the individual gas. \[P={{P}_{1}}+{{P}_{2}}+{{P}_{3}}.......\,.\] Daltons law of partial pressure follows by the mixture of non reacting gas but \[N{{H}_{3}}\]react with HCl gives \[N{{H}_{4}}Cl.\] \[N{{H}_{3}}+HCl\to N{{H}_{4}}Cl\] Hence, Daltons law of partial pressure is not applicable to \[N{{H}_{3}}+HCl.\]
