Study the reactions given below. State which of the following chemical reactions will take place or not,giving suitable reason for each:
$(a)$ $Zn(s) + CuSO_4(aq) \rightarrow ZnSO_4(aq) + Cu(s)$
$(b)$ $Fe(s) + ZnSO_4(aq) \rightarrow FeSO_4(aq) + Zn(s)$
$(c)$ $Zn(s) + FeSO_4(aq) \rightarrow ZnSO_4(aq) + Fe(s)$
$(a)$ $Zn(s) + CuSO_4(aq) \rightarrow ZnSO_4(aq) + Cu(s)$
$(b)$ $Fe(s) + ZnSO_4(aq) \rightarrow FeSO_4(aq) + Zn(s)$
$(c)$ $Zn(s) + FeSO_4(aq) \rightarrow ZnSO_4(aq) + Fe(s)$
(N/A) Zinc is more reactive than copper; therefore,it will displace copper from $CuSO_4$. This reaction will take place.
$(b)$ Iron is less reactive than zinc; therefore,it cannot displace zinc from zinc sulphate. This reaction will not take place.
$(c)$ Zinc is more reactive than iron; therefore,it will displace iron from $FeSO_4$. This reaction will take place.
