A) \[BeO\]and \[A{{l}_{2}}{{O}_{3}}\]
B) \[ZnO\]and \[F{{e}_{2}}{{O}_{3}}\]
C) \[CaO\]and \[C{{r}_{2}}{{O}_{3}}\]
D) \[BaO\]and\[{{U}_{3}}{{O}_{8}}\]
Correct Answer: B
Solution :
\[ZnO\]and\[F{{e}_{2}}{{O}_{3}}\]are reduced by carbon at higher temperature. This is because, at higher temperature, the value of\[\Delta G\]becomes more negative (according to Ellingham diagram
