Which of the foll A. 2AgNO3(aq) + Zn(s) → Zn(NO3)2(aq)+ 2Ag(s)
B. CuSO4(aq)+ Zn(s) → ZnSO4 (aq)+ Cu(s)
C. 2AgNO3(aq)+Fe(s) → Fe(NO3)2(aq) + 2Ag(s)
D. CuSO4(aq) + 2Ag(s) → Cu(s)+ Ag2SO4 (aq)
Among all the reactions, the reaction d is only not possible because silver is less reactive as compared to copper and hence it cannot displace copper from its salt.
So correct answer is d.
