Question 1
Consider two half-reactions: A²⁺ + 2e⁻ ⇌ A(s) E° = +0.76 V and B²⁺ + 2e⁻ ⇌ B(s) E° = -0.44 V. Which species would act as the reducing agent if combined in a galvanic cell?
💡 Hint: Compare E° values to determine the roles of oxidizing and reducing agents.
Question 2
Calculate the cell potential and determine spontaneity of the reaction between Ag⁺ and Cu with E° values of +0.80 V and -0.34 V respectively.
💡 Hint: Follow the formula for E°_cell using cathode and anode values.
