Question

Using a table of standard reduction potentials calculate the standard cell potential (electromotive force) in volts

for the following cell.


Cu + Cl2 = Cu2+ + 2Cl−

Calculate the standard free energy change in kJ/mol for the above cell reaction.

thanks so much theonlybeldin! =)

Answer 1

Eo (Cu/Cu2+) = -0.337 V, Eo (Cl2/Cl-) = +1.360 V, so Eo for the cell is +1.023 V

delta G = -nFEo = - (2) * (96500) (1.023) = -197.4 kJ/mol
