Question

CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s)

FeSO4(aq) + Zn(s) → ZnSO4(aq) + Fe(s)

On the basis of the above reactions, indicate which is most reactive and which is least reactive metal out of zinc, copper and iron.

Solution

In the first reaction, Fe displaces Cu from CuSO4 solution. So Fe is more reactive than Cu.
In the second reaction, Zn displaces Fe from FeSO4 solution. So Zn is more reactive than Fe.
Hence it can be concluded that Zn is the most reactive metal and Cu is the least 
reactive metal out of zinc, copper and iron.

  Is there an error in this question or solution?
