The reaction Cr2O3+2Al=Al2O3+2Cr is a :(a) Combination reaction(c) Decomposition reactionAl2O3 + 2Cr is a :(6) Double displacement reaction(d) Displacement reaction.​

Answer»

Answer:

CERTAIN amount of activation energy is essential for thermodynamically feasible reactions also.

In THERMITE process,

Cr2O3+2Al⟶Al 2O3+2Cr+Q

It is an EXOTHERMIC and spontaneous process. It requires more activation energy. At ROOM temperature it does not takes place as activation energy is LESS.
