The value of missing cell potential is - 0.04 V
What is cell potential ?
The cell potential (Ecell), is the measure of the potential difference between two half cells in an electrochemical cell.
Fe(III) / Fe(II) potential involves different chemical species in acidic and basic solution.
2FeO²⁻ + 3ClO⁻ + 2OH⁻ --> FeO₄²⁻ + 3Cl⁻ + H₂O
FeO₄²⁻ can easily oxidise water under acidic conditions.
Hence, The value of missing cell potential is - 0.04 V
