Solution

Answer :

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.
