    A)     

    B)

    C)

    D)

    Correct Answer: C

    Solution :

    \[p={{k}_{H}}\times \left( \frac{{{n}_{gas}}}{{{n}_{{{H}_{2}}O}}+{{n}_{gas}}} \right)\] \[={{k}_{H}}\left( 1-\frac{{{n}_{{{H}_{2}}O}}}{{{n}_{{{H}_{2}}O}}+{{n}_{gas}}} \right)\]           \[\Rightarrow \]\[p={{k}_{H}}-{{k}_{H}}\times {{\chi }_{{{H}_{2}}O}}\] \[p=(-{{k}_{H}})\times {{\chi }_{{{H}_{2}}O}}+{{k}_{H}}\]
