Which of the following reactions is not involved in serpeck's process of leaching of

A{l}_{2}{O}_{3}

from white bauxite ore?

Options

A $A{l}_{2}{O}_{3} + {N}_{2} + 3C\overset{\Delta}{\to}2AlN + 3CO$
B $Si{O}_{2} + C\overset{\Delta}{\to}Si + 2CO$
C $N{a}_{2}C{O}_{3} + A{l}_{2}{O}_{3}\overset{\Delta}{\to}2NaAl{O}_{2} + C{O}_{2}$
D $2Al{\left(OH\right)}_{3}\overset{\Delta}{\to}A{l}_{2}{O}_{3} + 3{H}_{2}O$

Correct answer

C. $N{a}_{2}C{O}_{3} + A{l}_{2}{O}_{3}\overset{\Delta}{\to}2NaAl{O}_{2} + C{O}_{2}$

Step-by-step solution

N{a}_{2}C{O}_{3} + A{l}_{2}{O}_{3}\overset{\Delta}{\to}2NaAl{O}_{2} + C{O}_{2}

is involved in Hall's process.
