Challenge Problems
Push your limits with advanced challenges
If the E° values for two reactions are E°(A/B) = +0.76 V and E°(C/D) = -0.34 V, will the reaction A + D → B + C occur spontaneously? Justify your answer.
💡 Hint: Consider how to calculate the overall E°.
Suppose you want to design a galvanic cell using zinc and copper with E° for Cu²⁺/Cu = +0.34 V and Zn²⁺/Zn = -0.76 V. What is the EMF? How would that affect the cell's operation?
💡 Hint: Remember to identify which electrode is the cathode and anode.
