    A)  greater than that for\[\text{CuO}\].

    B)  less than that for\[\text{CuO}\]

    C)  less than that for\[\text{ }\!\!~\!\!\text{ A}{{\text{g}}_{\text{2}}}\text{O}\]

    D)  equal to that for \[\text{CuO}\]

    Correct Answer: A

    Solution :

     The reduction of zinc oxide with coke occurs at temperature greater than that for CuO. \[ZnO+C\xrightarrow[>\,1000{{\,}^{o}}C]{\Delta }Zn+CO\]
