Question

The standard electrode potential (E0)

for tDaniel cell is +1.1V. Calculate the ∆G0
for the

Reaction: Zn(s) + Cu+2(aq)→Zn+2(aq) + Cu(s) (1F = 96500 C)​

Answer 1

HEYA GM ❤

★ E° = 1.1 Volt ; ∆G° = -n×F×E°

» n = no. of electrons dissipated

» n = no. of electrons dissipated » F = 96500 C

»» -∆G° = nFE°

»» -∆G° = nFE°= 2 × 96500 × 1.1

»» -∆G° = nFE°= 2 × 96500 × 1.1 = - 212.3 Kilo Joules

Hence... Standard free Energy change ( ∆G° ) is -212.3 KJ
