Question 53
GG - G1NAT2 marksNeeds review
In the given reaction,
2Fe²⁺ + 3H₂O → Fe₂O₃ + 6H⁺ + 2e⁻
consider ideal condition, take concentration of Fe²⁺ as 10⁻⁵ mol, E⁰ = 0.98 V and pH=6. The value of (2.303 × R × T)/F = 0.059 (where F is the Faraday constant). The value of Eₕ on the Fe²⁺ / hematite boundary at 25 °C is __________ V. [round off to 2 decimal places]
