Solution to All of 2005 #2 and Part (d) of 2004 #2

Below are the solutions to problem 2005 Free-Response Form A #2 and part (d) of 2004 Free-Response Form B #2. I really botched part (d) today in class, so I wanted to make sure that everyone saw the simplest and correct way to solve the problem. I am pleading temporary insanity for making the problem way harder than it had to be. Please finish 2006 Free-Response Form a #3 and 1993 Free-Response #2 for tomorrow. They will be checked for credit. Also have the Electrochemistry Packet complete and ready to turn in tomorrow for credit.
