Although thermodynamically feasible , in practices, magnesium metal are used for the reduction of almunia in the metallurgy of Al becauese.

A

reaction is slow

B

the tempature required is high

C

there are side reaction

D

magneaium oxide decmposes

Text Solution

Verified by Experts

The correct Answer is:
b
`(2)/(3) Al_(2)O_(3) + 2Mg rarr 2MgO + (4)/(3) Al`
The temperature required is so high that the process will be uneconomic and technologically diffcult.
