    For the cell,\[Tl\,|T{{l}^{+}}\,(0.001\,M)|\,\,|C{{u}^{2+}}(0.1)M\,\,|\,Cu\]\[{{E}_{cell}}\] at  \[{{25}^{o}}C\] is  \[0.83V.\] \[{{E}_{cell}}\] can be increased

    A)  by decreasing \[[C{{u}^{2+}}]\]

    B)  by increasing \[[C{{u}^{2+}}]\]

    C)  by increasing \[[T{{l}^{+}}]\]

    D)  none

    Correct Answer: B

    Solution :

                    \[{{E}_{cell}}={{E}^{o}}_{cell}+\frac{0.0592}{n}\log \frac{[C{{u}^{2+}}]}{{{[T{{i}^{+}}]}^{2}}}\] \[n=2\] \[\therefore \] According to above eq. \[{{E}_{cell}}\] can be increased by increasing \[[C{{u}^{2+}}]\]
