Question

20. Consider the following half-reactions at 298 K: + 2e- Fe Eored=-0.441 V Cd2++ Cd Eed-0.403 v A galvanic cell based on these haif-reactions is set up under standard conditions where each solutions is 1.00 L and each electrode weighs exactly 100.0 g. How much wil the Cd electrode weigh when the non- standard potential of the cell is 0.03195 V? Submit Answer Tries 0/3 21. A voltaic cell can be set up using the following pair of half-reactions at 298 K: I2 (s)+2e 2I (ag) Fe2+ (aq) + 2e- Fe (s) From the list below select and assign the oxidizing agent (OA) and reducing agent (RA) respectively: 111) Fe2+ IV) Fe O I/IV Submit Answer Tries 0/2

Explanation / Answer

for 21 question answer is last one

Since Reduction potential of Fe is less conpare to Iodine.

again Fe has below of Iodine in Electrochemical series So Feacts as Reducing agent where as Iodine acts as Oxidizing agent.
