What is change in free energy for galvanic cell?

ΔG = 0 ΔG > 0 ΔG < 0 None of these

ΔG < 0

For a galvanic cell, free energy decreases, i.e., ΔG < 0. Galvanic Cell: a galvanic cell is an electrochemical cell that uses the spontaneous chemical redox reaction to produce electrical energy (an electric potential). Galvanic cells require a negative Gibbs free energy value because this indicates a spontaneous reaction.
