Question

Analyze each cell reaction. Identify and write the half-reaction that occurs in the anode and in the cathode. Calculate the standard cell potential and describe the reaction whether it is spontaneous or nonspontaneous. Show your solution.

1. Li (s) + F2 (g) = Li+ (aq) + 2F- (aq)

2. Au3+ (aq) + Co (s) = Au (s) + Co2+ (aq)

3. 2 Al (s) + 3 i2 = 2 Al+3 (aq) + 6 i-1 (aq)

4. F2 (g) + 2Cl-1 (aq) = 2F-1 (aq) + Cl2 (g)

Answer 1

$Zn(s) = Zn_2^+ (aq) + (2e^-).$
