    Which of the following will form a cell with the highest voltage?

    A)  \[1M\,A{{g}^{+}},1M\,C{{o}^{2+}}\]

    B)  \[2M\,A{{g}^{+}},2M\,C{{o}^{2+}}\]

    C)  \[0.1M\,A{{g}^{+}},2M\,C{{o}^{2+}}\]

    D) \[2M\,A{{g}^{+}},0.1\,M\,C{{o}^{2+}}\]

    Correct Answer: D

    Solution :

    : \[E=E_{cell}^{o}+\frac{0.0591}{2}\log \frac{{{[Ag_{(aq)}^{+}]}^{2}}}{[Co_{(aq)}^{2+}]}\]
