The standard reduction potential values for the given half-reactions are:

$E_{{\mathrm{H}}^{+}/{\mathrm{H}}_2}^{\circ }=0.00\mathrm{V}$

$E_{{\mathrm{F}}_2/{\mathrm{F}}^{-}}^{\circ }=+2.87\mathrm{V}$

$E_{{\mathrm{Li}}^{+}/\mathrm{Li}}^{\circ }=-3.05\mathrm{V}$

$E_{{\mathrm{Cl}}_2/{\mathrm{Cl}}^{-}}^{\circ }=+1.36\mathrm{V}$

Lithium has the lowest standard reduction potential in the electrochemical series. Thus, the reduction of ${\mathrm{Li}}^{+}$ to $\mathrm{Li}$ exhibits the minimum standard reduction potential.

Answer: ${\mathrm{Li}}_{(\mathrm{aq})}^{+}+\overline{\mathrm{e}}\to {\mathrm{Li}}_{(\mathrm{s})}$
