Which energy conversion takes place in an operating galvanic cell?

A.Chemical potential energy is converted into electrical energy

B.Electrical energy is converted into chemical potential energy

C.Heat from burning fuel is converted into electrical energy by a turbine cycle

D.Light energy is converted into chemical bond energy

Explanation

Core Concept

A galvanic cell runs a spontaneous redox reaction whose negative ΔG leaves the system. Electrons released at the anode are pushed through the external circuit toward the cathode, and that directed flow is the electric current. The device harvests chemical bond energy as usable electrical work rather than heat.

Correct Answer

AChemical potential energy is converted into electrical energy
