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.
