    For a given reaction: \[M(x+n)+n{{e}^{-}}\xrightarrow{{}}{{M}^{x+}},{{E}^{-}}_{red}\] is known along with \[{{M}^{(x+n)}}\] and \[{{M}^{x+}}\] ion concentrations. Then

    A) n can be evaluated

    B) x can be evaluated

    C) \[\left( x+n \right)\] can be evaluated

    D) \[n,x,\left( x+n \right)\] can be evaluated

    Correct Answer: A

    Solution :

    [a] \[{{E}_{red}}=E_{red}^{{}^\circ }+\frac{0.059}{n}\log \frac{[{{M}^{(x+n)}}]}{[{{M}^{x+}}]}\]
