Calculate emf of cell at 25ÂºC Cell notation M|M2+0.01||M2+0.00001|M If value of E0cell is 4 volt (Given (RT/F) in 10 = 0.06) (A) 3.94 Volt (B) 4.06 Volt (C) 2.03 Volt (D) 8.18 Volt

Tardigrade Admin · Accepted Answer

E=E0-(0.059/2) log (10-4/10-2) E=4-0.03 log 10-2 4-0.06=3.94

Q. Calculate emf of cell at 25ºC
Cell notation
$M ∣ ∣ M_{0.01}^{2 +} ∣ ∣ ∣ ∣ M_{0.00001}^{2 +} ∣ ∣ M$
If value of E⁰_cell is 4 volt (Given $\frac{RT}{F}$ in 10 = 0.06)

3.94 Volt

4.06 Volt

2.03 Volt

8.18 Volt

$E = E^{0} - \frac{0.059}{2}$ log $\frac{1 0 ^{- 4}}{1 0 ^{- 2}}$
$E = 4 - 0.03$ log $1 0^{- 2}$
$4 - 0.06 = 3.94$
