Chem 123 Spring 2006 Assignment 3 Due: Friday July 21 1 Given that E o = +0.04 V for the reaction: Cd 2+ + Fe(s) Fe 2+ + Cd(s), what is the standard reduction potential for Cd 2+ + 2e Cd(s)? (Find E o for the Fe 2+ /Fe half-reaction in Appendix D.) 2. Consider the following reactions: (1) Pb(s) + Co 2+ (aq) Pb 2+ (aq) + Co(s) (2) PbSO 4 (s) + Ni(s) Ni 2+ (aq) + Pb(s) + SO4 2 (aq) (3) IO 3 (aq) + 6H + (aq) + 5Ag(s) ½ I 2 (s) + 3H 2 O(l) + 5Ag + (aq) (a) What is E o for each of the reactions? Look up standard reduction potentials in Appendix D.

Unformatted text preview: (b) In which direction does each reaction proceed spontaneously at standard state conditions? (c) What is the equilibrium constant in each case? 3. Calculate E o for the reaction Cu(s) + 2Ag + (aq) → Cu 2+ (aq) + 2Ag(s). Look up standard reduction potentials in Appendix D. 4. Consider the galvanic cell Cu(s) | Cu 2+ (aq, 0.50 M) || Ag + (aq, 1.0×10 − 6 M) | Ag(s). What is the equation for the spontaneous cell reaction? What is E for this cell?...
