Current Question (ID: 18217)

Question:

$\text{The electricity required in coulombs for the oxidation of 1 mole of } \text{FeO to } \text{Fe}_2\text{O}_3 \text{ is:}$

Options:

1. $964.87 \text{ C}$
2. $96487 \text{ C}$
3. $96.487 \text{ C}$
4. $9.6487 \text{ C}$

Solution:

$\text{Use Faraday's law of electrolysis}$ $\text{According to the question,}$ $\text{Fe}^{2+} \rightarrow \text{Fe}^{3+} + \text{e}^- $ $\text{Electricity required for the oxidation of 1 mol of FeO to } \text{Fe}_2\text{O}_3 = 1 \text{ F}$ $= 96487 \text{ C}$
