Emf of the cell is +1.10 V
Explanation:
Using Nernst equation :
where,
F = Faraday constant = 96500 C
R = gas constant = 8.314 J/mol.K
T = room temperature =
n = number of electrons in oxidation-reduction reaction = 2
= standard electrode potential of the cell =
= emf of the cell
Now put all the given values in the above equation, we get:
