  • question_answer For the cell \[T1|T{{1}^{+}}(0.001\,\,M)||C{{u}^{2+}}(0.1\,\,M)|Cu\]. \[{{E}_{cell}}\,\,at\text{ }25{}^\circ C\text{ }is\text{ }0.83\text{ }V\] which can be increased-
    [a] \[by\,\,increasing\,\,C{{u}^{2+}}\]
    [b] \[by\,\,increasing\,\,[T{{1}^{+}}]\]
    [c] \[by\,\,decreasing\,\,[C{{u}^{2+}}]\]
    [d] \[by\,\,decreasing\,\,[T{{1}^{\text{+}}}]\]

    A) a, c                              

    B) a, d

    C) a, b, d              

    D) a, c, d

    Correct Answer: B

    Solution :

    \[{{E}_{cell}}-{{E}^{{}^\circ }}_{cell}+\frac{0.0591}{2}\,log,\,\,\frac{\left[ C{{u}^{2+}} \right]}{{{\left[ T{{\ell }^{+}} \right]}^{2}}}\]
