Question

Consider the following reduction processes :

$${{Al}^{3 +} + 3e^{-} \rightarrow Al(s),E^{\circ} = - 1.66\text{ }V }{{Fe}^{3 +} + e^{-} \rightarrow {Fe}^{2 +},E^{\circ} = + 0.77\text{ }V }{{Co}^{3 +} + e^{-} \rightarrow {Co}^{2 +},E^{\circ} = + 1.81\text{ }V }{{Cr}^{3 +} + 3e^{-} \rightarrow Cr(s),E^{\circ} = - 0.74\text{ }V }$$The tendency to act as reducing agent decreases in the order :
