JEE Main & Advanced Chemistry Electrochemistry / विद्युत् रसायन Question Bank Cell constant and Electrochemical cells

  • question_answer
    At 25°C specific conductivity of a normal solution of KCl is 0.002765 mho. The resistance of cell is 400 ohms. The cell constant is                                          [Pb.PMT 2004]

    A)                 0.815    

    B)                 1.016

    C)                 1.106    

    D)                 2.016

    Correct Answer: C

    Solution :

               Cell constant \[=\frac{\text{Specific conductivity}}{\text{Observed conductance}}\]                                 \[=\frac{0.002765}{1/R}\] =0\[.002765\times 400=1.106\].
