Chem 2C(B) – S04 2 Practice Midterm 1 Name 2 Each multiple choice question is worth 10 points. Circle the BEST answer. Only ONE answer will be graded--if two are circled--the answer will be counted as WRONG! 1. Consider the following reaction: Cd(s) + 2AgCl(s) ––> Cd 2+ (aq) + 2Ag(s) + 2Cl (aq) In this reaction, the reducting agent is (a) Cd(s) (b) AgCl(s) (c) Cd 2+ (d) Ag(s) (e) Cl (aq) 2. The equilibrium constant for the reaction 2Hg(l) + 2Cl (aq) + Ni 2+ (aq) Æ Ni(s) +Hg 2 Cl 2 (s) is 5.6 x 10 -20 at 25 ˚ C. Calculate E ˚ for a cell utilizing this reaction. (a) —0.25 V (b) +0.57 V (c) +1.14 V (d) —0.57 V (e) —1.14 V 3. The standard potential of the Ag + /Ag electrode is +0.80 V and the standard potential of the cell Fe(s)|Fe 2+ (aq) ||Ag + (aq)|Ag(s) is +1.24 V. What is the standard potential of the Fe 2+ /Fe electrode? (a)
