Vedclass · Answer

(A) The reactivity of a metal is directly related to its ability to lose electrons,which is measured by its standard oxidation potential. Since $E^{0}_{Oxidation} = -E^{0}_{Reduction}$,a more negative $E^{0}_{Reduction}$ value indicates a higher tendency to lose electrons (higher oxidation potential). Comparing the given values: $A = -3.05 \ V$,$B = -1.66 \ V$,$C = -0.40 \ V$,and $D = 0.80 \ V$. Element $A$ has the most negative reduction potential,meaning it is the most easily oxidized and therefore the most reactive.

The standard electrode potentials $(E^{0}_{Red})$ of four elements $A, B, C,$ and $D$ are $-3.05 \ V, -1.66 \ V, -0.40 \ V,$ and $0.80 \ V$ respectively. Which of the following is the most reactive?
