Question 1
Consider a galvanic cell with the following half-reactions:
Ag⁺ + e⁻ → Ag (E° = +0.80 V)
Zn²⁺ + 2e⁻ → Zn (E° = -0.76 V)
Calculate E°_cell and discuss its implications for the spontaneity of the reaction.
💡 Hint: Calculate the cell potential using E° values.
Question 2
Discuss how the E° values for two substances influence their practical uses as electrodes in battery technology.
💡 Hint: Reflect on what these values suggest about electrode behavior.
