Question: Q10. Write the relation between the energy changes for an electrochemical cell and its potential (AE), operating reversibly (no current flows), (3points). Q11. Repeat Q10

Q10. Write the relation between the energy changes for an electrochemical cell and its potential (AE), operating reversibly (no current flows), (3points). Q11. Repeat Q10 but under standard conditions, (3points). Q12. What does it mean when the energy change of a reversible electrochemical cell is negative? Problems: Pr.1 If you have a mixture of a) Cu+2/H+ b) Fe+2/H+ And you provide electrons for both mixtures, which ion will take the electrons in each mixture? (8 pints)
