Q.1. Compare betwEEn galvanic and electrolytic cells.
Q.2. Explain électrolysis of molten and aqueous NaCl.
Q.3. Detemine plIfor the following cell:
ZnZn (IM) || H+ (test solution)/H (1 atin)/Pt
Given, Ea =0,50 V and Ea =0,76 V
04. Calculate Ean using AGr values for the folowing reaction Conmment whether the reaction
is spontancous ornot
Zn(s) + Clk (g) – Zn (a) + 2C (ag)
where AG values are for: Zni(s)- 0, Ch (g)- 0, Zr"(a = 147 kj & CI (ax)- -131 kj
Q.5. Draw the voltaie cell with folowing otation and comment whether the cell reaction is.
sportaneousor t? If rol, what skould you do?
Cu (s)/ Cư (ag) l+ (test solution H(1 atm/Pt
where Ecc = 0.34 V & E° thy t=0.0 V
Q.6. Balance the following net reaction for oxidation of Zn by IINO (acidic solution) using haif
reaction method:
Zn(s) + NOs (ac) = Zr"(ac) + NH (aq)
Q.7. Consider the foliowing cel reaction.
Cư" (ag) + 21(aq) Cus) + b(s)
Given, Cu* (ac)/Cu(s) = 0.34 V
L(g) //(ag) = 0.54 V
a Wite down half-cell reactions for the above raction
b Determine whether the above reaction is spontaneous or not.
