Chem 312 Winter 2010 "Chem–Talk" #2 Key Fri, January 15, 2010 1a. Using the Table below calculate Δ E 1/2 for the reaction between Zn 2+ (converting to Zn 0 ) and Fe 2+ (converting to Fe 3+ ). Δ E 1/2 = E 1/2 (oxidant) – E 1/2 (reductant) = –0.76 V – +0.77 V = –1.53 V 1b. Would this reaction be favored? yes no 1c. Use the Table above to determine whether F would be capable of oxidizing Fe 2+ ? yes no
