Unformatted text preview: Version 145 Quiz 5 laude (51635) 1 This print-out should have 8 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 5.0 points Consider the following table of half cell reduc- tion potentials. Half reaction E o A + + e - A- . 5 B + + e - B . C + + e - C 1 . Which of the following statements is not true? 1. Half cell oxidation potentials are easily determined from the table. 2. The table provides no evidence that stan- dard conditions are used. correct 3. The reduction of B + is consistent with a half cell reaction that serves as a reference. 4. As written, C + is the strongest oxidizing agent. Explanation: The naught, o , in E o is indicative of stan- dard conditions. 002 5.0 points Consider a voltaic cell based on the redox reaction Zn + Cl 2 ZnCl 2 . The half cell reaction occuring at the anode is 1. Zn Zn 2+ + 2 e correct 2. None of these 3. Cl 2 + 2 e 2 Cl 4. Zn 2+ + 2 Cl ZnCl 2 Explanation: Oxidation (loss or production of e ) always occurs at the anode....
