    For redox reaction,\[F{{e}^{2+}}(aq)+C{{r}_{2}}O_{7}^{2-}(aq)+{{H}^{+}}(aq)\xrightarrow{{}}\] \[F{{e}^{3+}}(aq)+C{{r}^{3+}}(aq)+{{H}_{2}}O(l)\] The coefficients of \[F{{e}^{2+}},C{{r}_{2}}O_{7}^{2-}\] and \[{{H}^{+}}\] in the balanced reaction are

    A)  \[6,1,14\]                           

    B)  \[3,2,6\]

    C)  \[2,3,6\]            

    D)  \[6,4,12\]

    Correct Answer: A

    Solution :

                    \[6F{{e}^{2+}}(aq)+C{{r}_{2}}O_{7}^{2-}(aq)+14{{H}^{+}}(aq)\xrightarrow{{}}\] \[6F{{e}^{3+}}(aq)+2C{{r}^{3+}}(aq)+7{{H}_{2}}O(l)\]
