Challenge Problems
Push your limits with challenges.
Question 1
Consider two reactions: A⁺/A with E° = +0.50 V and B⁺/B with E° = -0.80 V. Calculate the E°_cell if A is reduced and B is oxidized.
💡 Hint: Identify which species acts as anode and cathode before making the calculation.
Question 2
A certain half-cell has an E° of +0.20 V. If the other half-cell connected is the SHE, determine the potential for the full cell and indicate its spontaneity.
💡 Hint: Consider the reference value of SHE in your calculation.
