The value of Delta_fG^(Theta)for formation of Cr_2 O_3is – 540 kJ "m

1.	The value of Delta_fG^(Theta)for formation of Cr_2 O_3is – 540 kJ "mol"^(-1)and that of Al_2 O_3is – 827 kJ "mol"^(-1) . Is the reduction of Cr_2 O_3possible with Al ?
Answer» REDUCTION of `Cr_2O_3` by AL will TAKE place Oxidation of `Cr_2O_3` by Al will take place NEITHER oxidation nor reduction take place REACTION is not feasible Answer :A
