For the following galvanic cell Cu2+ + e - Cu+ and Au3+ + 3e - Au?

Question

1. Balance the cell reaction

2. Determine E

3. Calculate max amount of work that can be obtained

(use std electrode potential table to obtain data where necessary)

Answer 1

1. Au3+ + 3 Cu+ -> Au + 3Cu2+

2. -0,16 + 1,52 = 1,36 V

3. Are you talking about free energy? In that case it is G=-392 kJ
