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

  • question_answer
    The relationship between standard reduction potential of cell and equilibrium constant is shown by        [MP PET 2002]

    A)                 \[E_{cell}^{0}=\frac{n}{0.059}\log {{K}_{c}}\]      

    B)                 \[E_{cell}^{0}=\frac{0.059}{n}\log {{K}_{c}}\]

    C)                 \[E_{cell}^{0}=0.059\,n\,\log {{K}_{c}}\]

    D)                 \[E_{cell}^{0}=\frac{\log {{K}_{c}}}{n}\]

    Correct Answer: B

    Solution :

                    \[E_{\text{cell}}^{o}=\frac{2.303\,\,RT}{nF}\log \,K=\frac{0.0591}{n}\log \,{{K}_{c}}\,at\,\,298K\].
