Solution. Reduction of Al2O3 is not performed by carbon due to two primary reasons which are:. Very high temperatures around 2100 degree celcius is required for the carbothermic reduction. Aluminium Oxide is a very stable oxide and lies below the the oxidation line of carbon in Ellingham Diagram hence Al2O3 cannot be reduced by carbon as it is ...
The bauxite powder is mixed with carbon and heated under high temperature (above 1800^circ C) and a current of nitrogen is passed. Through this process aluminium nitride is obtained along with water and carbon monoxide. For the given question, let's understand how the process works and then identify the reaction matching the process.
