    Represent the cell in which of the following reaction takes place? \[\text{N}{{\text{a}}_{\text{2}}}{{\text{S}}_{4}}{{\text{O}}_{6}}\]                                                 \[\text{NaHS}{{\text{O}}_{3}}\] Calculate,\[\text{Sr}\] if \[\text{Sr}\]

    A) 1.6395V               

    B) 0.6395V

    C) 0.06395V             

    D) -1.6395V

    Correct Answer: A

    Solution :

    The cell can be written as \[\therefore \] \[{{p}_{1}}{{v}_{1}}={{n}_{1}}R{{T}_{1}}\] \[{{p}_{1}}=\frac{{{n}_{1}}RT}{V},similarly\,\,{{p}_{2}}=\frac{{{n}_{2}}R{{T}_{2}}}{V}\] \[\frac{{{p}_{1}}}{{{p}_{2}}}=\frac{{{n}_{1}}R{{T}_{1}}V}{{{n}_{2}}R{{T}_{2}}V}=\frac{{{n}_{1}}{{T}_{1}}}{{{n}_{2}}{{T}_{2}}}\]
