BIS 103                     Name____________________________________ Section 1 Last First MI Instructor: Roy H. Doi Final Examination ( Form A ) December 14, 2007 Be sure to write your name, ID number and Form A on the Scantron Sheet There are 12 pages to this exam including the front page. Count the pages to make certain that all pages are present. There are 50 questions. Each question has only ONE best/complete answer. Each question is worth 4 points. Please mark the Scantron sheet carefully with a #2 pencil. Be sure to turn in this exam along with your Scantron sheet. ∆G‘o = -nF∆E’o ∆G‘o = -RTlnK’eq ∆G = ∆G‘o + RTln[Products]/[Reactants] E = E’o + RT/nF x ln[Electron Acceptor]/[Electron Donor] Faraday constant, F = 96,500 J/V/mol Gas constant, R = 8.315 J/mol K 25°C = 298 K Honor Code: My signature below affirms that I wrote this exam in the spirit of the honor system of UC Davis.
