Verified Solution • 2025–26 Session moderate

For the redox reaction Zn(s) + Cu²⁺(0.1 M)

\to

Zn²⁺(1M) + Cu(s) taking place in a cell,

E_{c e l l}^{o}

is 1.10 volt. E_cell for the cell will be (

2.303 \frac{R T}{F}

= 0.0591)

Accepted Answer

E_{c e l l} = {E^{\circ}}_{c e l l} + \frac{0.059}{n} \log \frac{[C u^{+ 2}]}{[Z n^{+ 2}]}

= 1.10 + \frac{0.059}{2} \log [0.1]

= 1.10 - 0.0295

= 1.07 V
