Arrange these metals in order of increasing reducing power.
$[\text{Fe}^{2+}\xrightarrow{ \ \ \ \ \ \ }\text{Fe}^{3+}+\text{e}^-]\times5\ \cdots\text{(i)}$
$5\text{e}^-+8\text{H}^++\text{MnO}_4^-\xrightarrow{ \ \ \ \ \ \ }\text{Mn}^{2+}+4\text{H}_2\text{O} \ \cdots\text{(ii)}$
Adding (i) and (ii), we get
$5\text{Fe}^{2+}+8\text{H}^++\text{MnO}_4^-\xrightarrow{ \ \ \ \ \ \ }\text{Mn}^{2+}+4\text{H}_2\text{O} \ +5\text{Fe}^{3+}$

During the reaction, temperature rises from 298K to 299K. If the heat superb, of the bomb calorimeter is 20.7kJ/ K, then what is the enthalpy change for the shove reaction at 298K and 1atm?$\text{K}_\text{b}=\frac{[\text{M}^+][\text{OH}^-]}{[\text{MOH}]}$
