alleryFor the cell Zn | Zn²⁺ (1 M) || Cu²⁺ (1 M) | Cu, with E°(Zn) = -0.76 V, E°(Cu) = +0.34 V, E_cell:
A-0.42 V
B+1.10 V
C-1.10 V
D+0.42 V
Answer & Solution
Correct answer: B. +1.10 V
E°_cell = E°_cathode - E°_anode = 0.34 - (-0.76) = +1.10 V. Positive value confirms spontaneous direction
this is the standard Daniell cell.
