ΔG° and E° can be said to measure the same thing, and are convertible by the equation

ΔG° = −nFE⁰cell 

where n is the total number of moles of electrons being transferred, and F is the Faraday constant 9.64853415 ✕ 104 C/mol. The free energy (ΔG°) of a spontaneous reaction is always negative.

For each of the electrochemical cells below, calculate the free energy of the system and state whether the reaction is spontaneous or non-spontaneous as written based on the cathode and anode assignment given.

(a) The cathode is Ni(II) and the anode is Cd(II).

free energy--> kJ

(b) The cathode is Mn(II) and the anode is Ti(III).

free energy--> kJ

(c) The cathode is Au(III) and the anode is Ag(I).

free energy --> kJ
