The reaction which is not involved in thermite process: (a) 3Mn O 8Al 9Mn 4Al O + ¾¾® + (b) Cr O 2Al 2Cr Al O + ¾¾® + (c) 2Fe Al O Fe O 2Al + ¾¾® + (d) B O 2Al 2B Al O + ¾¾® +
Answer
C
Explanation
In thermite process, aluminium is used for the reduction of metal oxides to their corresponding metallic states. But the reaction given in option C is not the reduction of metal oxide. Therefore, it doesn’t occur in thermite process.
