Vedclass · Answer

(C) The thermite process involves the reduction of metal oxides by aluminum $(Al)$ to produce the metal and aluminum oxide $(Al_2O_3)$.This is a highly exothermic reaction used for welding.In the reaction $2Fe + Al_2O_3 \rightarrow 2Al + Fe_2O_3$,aluminum is being oxidized and iron is being reduced,which is the reverse of the thermite process.Since $Al$ is a stronger reducing agent than $Fe$,$Al$ can reduce $Fe_2O_3$ to $Fe$,but $Fe$ cannot reduce $Al_2O_3$ to $Al$ under standard conditions.

Which of the following reactions does not take place in the thermite process?
