Chem 165 Class 28 Chapter 19: Electrochemistry Objective today: 1. Relate reduction potentials to strengths of oxidizing/reducing agents. 2. Introduce the Nernst equation and the effects of concentration on cell potentials. Text: Chapter 19: Section 3 – 5; Next class: Chapter 19: Section 6 – 8 ARIS: Chapter 19-A: assignment due Tuesday (4/28) at 10:00 pm CDT ARIS: Chapter 19-B: assignment due Friday (5/1) at 6:00 pm CDT Upcoming (final) ARIS assignments for the course: Suggested Problems (Classes 27 & 28): 11, 12, 14, 15, 16, 18, 22, 23, 24, 30, 34 Caption : The thermite reaction is another example of a (highly exothermic) redox reaction: Fe 2 O 3 ( s ) + 2Al(s) Al 2 O 3 ( s ) + 2Fe( s ). In this reaction, rust [Fe 2 O 3 ( s )] reacts with aluminum powder [Al( s )] to produce alumina [Al 2 O 3 ( s )] and (ultimately) solid iron [Fe( s )], although the excessive heat generated from this exothermic process initially produces molten iron [Fe( l )]. Of course, the energy generated here cannot be captured to do work, as is the case when redox reactions are carried out in galvanic cells. Final Exam: Wednesday, May 6, 7:00 – 9:00 pm, same room/seat assignments Review session: Sunday, May 3, 6:00 pm, 1002 Gilman Evaluations (For TA/recitation and for H. Stauffer/lecture): Available on WebCT this Friday (4/24) at 8:00 am; Due next Friday (5/1) at 8:00 am
