The reaction, Cr_2O_3 + 2Al to Al_2O_3 + 2Cr , (Delta_rG^(0) = - 421 k – InterviewSolution

1.	The reaction, Cr_2O_3 + 2Al to Al_2O_3 + 2Cr , (Delta_rG^(0) = - 421 kJ) is thermodynamically feasible as is apparent from the Gibb's energy value. Why does it not take place at room temperature ?
Answer» Solution :The reaction does not takes place at ROOM temperature because of high activation ENERGY through reaction is thermodynamically feasible. Thus, heating is requied to overcome activation energy.
