Challenge Problems
Push your limits with challenges.
Question 1
Calculate the overall standard cell potential if given two half-reaction potentials, E°(A) = 0.40 V and E°(B) = -0.50 V. Identify each as anode or cathode.
💡 Hint: Remember, the cell potential combines the cathode's reduction potential minus the anode's oxidation.
Question 2
Discuss what a negative ΔG° suggests for a reaction's E°cell when given a scenario where the Gibbs free energy is measured at 100 kJ.
💡 Hint: Connect ΔG and E°cell through their relationship.
