`Al_(2) O_(3)` can't be reduced by carbon to get Al mental. Explain.

Why Al cannot be reduced by carbon?

Why Al cannot be reduced by carbon?

Al_(2)O_(3) reacts with

Al_(2)O_(3) is reduced by electrolysis at low potentials and high current. If 4.0 xx 10^(4) amperes of currernt is passed through molten Al_(2)O_(3) for 6 hours, what mass of aluminium is produced? (Assume 100 % current efficiency, At. Mass of Al = 27 u )

Assertion : Al_(2)O_(3) is converted into Al by reduction with carbon at high temp. Reason : Carbon has greater affinity for oxygen than aluminium.
