8. An electrochemical cell of notation Pd | Pd2+|| Cu2+ | Cu has an Eº = -0.65 V. If we know that the standard reduction potential of Cu2+/Cu is Eº = 0.34 V, what is the standard reduction potential for Pd2+/Pd? a) -0.99 V d) 0.62 V b) -0.31 V e) +0.99 V c) +0.31 V 9. Cu(s) + 2 Agt Cu2+ + 2 Ag(s) If the equilibrium constant for the reaction above is 3.7 x 1015, which of the following correctly describes the standard voltage, Eº, and the standard free energy change, AGⓇ, for this reaction? (A) Eº is positive and AGº is negative. (B) Eº is negative and AGº is positive. (C) Eº and AGº are both positive. (D) Eº and AGº are both negative. (E) Eº and AGº are both zero
