Answer to Question #184026 in General Chemistry for Aich80

Question #184026

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.


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)
