Equivalent weight of in the reaction is: (M = mol. wt.) — Redox Reactions and Volumetric Analysis Chemistry Question
Question
Equivalent weight of $Fe_2O_3$ in the reaction $Fe_2O_3 + 3CO \rightarrow 2Fe + 3CO_2$ is: (M = mol. wt.)
Answer: C
💡 Solution & Explanation
Iron in $Fe_2O_3$ is $+3$ and in $Fe$ is $0$. Change in O.S. per $Fe$ atom = 3. Since there are 2 $Fe$ atoms in $Fe_2O_3$, total change ($n$-factor) = 6. Eq. wt = M/6. [1, 4]
