Which of the following reactions exhibit minimum standard reduction potential?

Step-by-step solution

The standard reduction potential E^ is a measure of the tendency for a species to gain electrons. Comparing the given reactions: For the standard hydrogen electrode, 2 H ⁺_ ( aq ) + 2 e ^- H _ 2( g ) , E^ = 0.00~ V . F _ 2( g ) + 2 e ^- 2 F ⁻_ ( aq ) has E^ = +2.87~ V . Li ⁺_ ( aq ) + e ^- Li _ ( s ) exhibits the most negative value, E^ = -3.05~ V . Cl _ 2( g ) + 2 e ^- 2 Cl ⁻_ ( aq ) has E^ = +1.36~ V . The minimum standard reduction potential corresponds to the lithium reduction reaction. Final answer: C
