Answer #1

anode : oxidation takes place

Zn (s) -------------------> Zn+2 (aq) + 2e ,   E0Zn+2/Zn = -0.76

cathode : reduction takes place

Br2 (aq)+ 2e- --------------------> 2 Br- (aq) , E0Br-/Br2 = +1.07

net reaction :

Zn (s) + Br2 (aq) -----------------> Zn+2 (aq) + 2 Br- (aq)

E0cell= E0cathode- E0anode

E0cell= E0Br-/Br2 - E0Zn+2/Zn

          = 1.07 - (-0.76)

          = 1.83 V

E0cell = 1.83 V
