Vedclass · Answer

(B) The alumino-thermic process (thermite process) is used for the extraction of metals like $Cr$,$Mn$,and $Fe$ from their oxides.These metals have a high affinity for oxygen,making their oxides very stable and difficult to reduce using common reducing agents like carbon or hydrogen.Aluminum acts as a strong reducing agent because the formation of $Al_2O_3$ is highly exothermic,providing the necessary energy for the reduction process.Example: $Cr_2O_3 + 2Al 	o Al_2O_3 + 2Cr$ $(\Delta H = -ve)$.
