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

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

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

    C)  by increasing\[[T{{i}^{+}}]\]

    D)  none

    Correct Answer: B

    Solution :

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