    Reaction that takes place at graphite anode in dry cell is:    

    A)  \[M{{n}^{+}}+2{{e}^{-}}\xrightarrow{{}}Mn(s)\]

    B)  \[Mn(s)+\xrightarrow{{}}M{{n}^{+}}+{{e}^{-}}+1.5V\]

    C)  \[Z{{n}^{2+}}(s)+2{{e}^{-}}\xrightarrow{{}}Zn(s)\]

    D)  \[Zn(s)\xrightarrow{{}}Z{{n}^{2+}}+2{{e}^{-}}\]                                   

    Correct Answer: D

    Solution :

                    The reaction which occurs at anode is \[Zn(s)\xrightarrow{{}}Z{{n}^{2+}}(aq)+2{{e}^{-}}\]
